•
1.25 W Into 8-Ω From a 5-V Supply at THD = 1%
differential amplifier designed to drive a speaker with
at least 8-Ω impedance while consuming less than 37
mm2 (ZQV package option) total printed-circuit-board
(PCB) area in most applications. This device operates
from 2.5 V to 5.5 V, drawing only 1.7 mA of quiescent
supply current. The TPA6205A1 is available in the
space-saving 2-mm × 2-mm MicroStar Junior BGA
package, and the space saving 3-mm × 3-mm QFN
(DRB) package.

8 Parameter Measurement Information
All parameters are measured according to the conditions described in the Specifications section.
9 Detailed Description
9.1 Overview
The TPA6205A1 is a 1.25-W mono fully differential amplifier. The devices operates in the range of 2.5 V to 5.5 V
and with at least 8-Ω impedance load. It's fully differential input allows it to avoid using input coupling capacitors
and improves its RF-immunity.

9.3 Feature Description
9.3.1 Fully Differential Amplifiers
The TPA6205A1 is a fully differential amplifier with differential inputs and outputs. The fully differential amplifier
consists of a differential amplifier and a common-mode amplifier. The differential amplifier ensures that the
amplifier outputs a differential voltage that is equal to the differential input times the gain. The common-mode
feedback ensures that the common-mode voltage at the output is biased around VDD/2 regardless of the
common-mode voltage at the input.
9.3.1.1 Advantages of Fully Differential Amplifiers
•
Input coupling capacitors not required: A fully differential amplifier with good CMRR, like the TPA6205A1,
allows the inputs to be biased at voltage other than mid-supply. For example, if a DAC has mid-supply lower
than the mid-supply of the TPA6205A1, the common-mode feedback circuit adjusts for that, and the
TPA6205A1 outputs are still biased at mid-supply of the TPA6205A1. The inputs of the TPA6205A1 can be
biased from 0.5 V to VDD – 0.8 V. If the inputs are biased outside of that range, input coupling capacitors are
required.
•
•
Mid-supply bypass capacitor, C(BYPASS), not required: The fully differential amplifier does not require a bypass
capacitor. This is because any shift in the mid-supply affects both positive and negative channels equally and
cancels at the differential output. However, removing the bypass capacitor slightly worsens power supply
rejection ratio (kSVR), but a slight decrease of kSVR may be acceptable when an additional component can be
eliminated (see Figure 17).
Better RF-immunity: GSM handsets save power by turning on and shutting off the RF transmitter at a rate of
217 Hz. The transmitted signal is picked-up on input and output traces. The fully differential amplifier cancels
the signal much better than the typical audio amplifier.

Feature Description (continued)
9.3.2 Fully Differential Amplifier Efficiency and Thermal Information
Class-AB amplifiers are inefficient. The primary cause of these inefficiencies is voltage drop across the output
stage transistors. There are two components of the internal voltage drop. One is the headroom or DC voltage
drop that varies inversely to output power. The second component is due to the sinewave nature of the output.
The total voltage drop can be calculated by subtracting the RMS value of the output voltage from VDD. The
internal voltage drop multiplied by the average value of the supply current, IDD(avg), determines the internal power
dissipation of the amplifier.
An easy-to-use equation to calculate efficiency starts Although the voltages and currents for SE and BTL out as
being equal to the ratio of power from the are sinusoidal in the load, currents from the supply power supply to the
power delivered to the load. To are very different between SE and BTL accurately calculate the RMS and
average values of configurations. In an SE application the current power in the load and in the amplifier, the
current and waveform is a half-wave rectified shape, whereas in voltage waveform shapes must first be
understood BTL it is a full-wave rectified waveform. This means (see Figure 27). RMS conversion factors are
different. Keep in mind that for most of the waveform both the push and pull transistors are not on at the same
time, which supports the fact that each amplifier in the BTL device only draws current from the supply for half the
waveform. Equation 1 through Equation 7 are the basis for calculating amplifier efficiency.

Table 2 employs Equation 7 to calculate efficiencies for four different output power levels. Note that the efficiency
of the amplifier is quite low for lower power levels and rises sharply as power to the load is increased resulting in
a nearly flat internal power dissipation over the normal operating range. Note that the internal dissipation at full
output power is less than in the half power range. Calculating the efficiency for a specific system is the key to
proper power supply design. For a 1.25-W audio system with 8-Ω loads and a 5-V supply, the maximum draw on
the power supply is almost 1.8 W.
A final point to remember about Class-AB amplifiers is how to manipulate the terms in the efficiency equation to
the utmost advantage when possible. Note that in Equation 7, VDD is in the denominator. This indicates that as
VDD goes down, efficiency goes up.
Equation 8 is a simple formula for calculating the maximum power dissipated, PDmax, may be used for a

The maximum ambient temperature depends on the heat sinking ability of the PCB system. The derating factor
for the 2 mm × 2 mm Microstar Junior package is shown in the dissipation rating table. Converting this to θJA is
shown in Equation 9:
1

QJA
=
=
Derating Factor 0.0088
= 113°C / W
(9)
Given θJA, the maximum allowable junction temperature, and the maximum internal dissipation, the maximum
ambient temperature can be calculated with Equation 10. The maximum recommended junction temperature for
the TPA6205A1 is 125°C.
TAMax = TJMax - QJAPDmax
= 125 -113(0.634) = 53.3°C
(10)
Equation 10 shows that the maximum ambient temperature is 53.3°C at maximum power dissipation with a 5-V
supply. Table 2 shows that for most applications no airflow is required to keep junction temperatures in the
specified range. The TPA6205A1 is designed with thermal protection that turns the device off when the junction
temperature surpasses 150°C to prevent damage to the IC. Also, using more resistive than 8-Ω packages, it is
good practice minimize the speakers dramatically increases the thermal performance by reducing the output
current.
9.3.3 Differential Output Versus Single-Ended Output
Figure 28 shows a Class-AB audio power amplifier (APA) in a fully differential configuration. The TPA6205A1
amplifier has differential outputs driving both ends of the load. There are several potential benefits to this
differential drive configuration, but initially consider power to the load. The differential drive to the speaker means
that as one side is slewing up, the other side is slewing down, and vice versa. This in effect doubles the voltage
swing on the load as compared to a ground referenced load. Plugging 2 × VO(PP) into the power equation, where
voltage is squared, yields 4× the output power from the same supply rail and load impedance (see Equation 11).

SLOS490C –JULY 2006–REVISED NOVEMBER 2015
In a typical wireless handset operating at 3.6 V, bridging raises the power into an 8-Ω speaker from a singled-
ended (SE, ground reference) limit of 200 mW to 800 mW. In sound power that is a 6-dB improvement—which is
loudness that can be heard. In addition to increased power there are frequency response concerns. Consider the
single-supply SE configuration shown in Figure 29. A coupling capacitor is required to block the DC offset voltage
from reaching the load. This capacitor can be quite large (approximately 33 μF to 1000 μF) so it tends to be
expensive, heavy, occupy valuable PCB area, and have the additional drawback of limiting low-frequency
performance of the system. This frequency-limiting effect is due to the high pass filter network created with the
speaker impedance and the coupling capacitance and is calculated with Equation 12.

fc =
2pRLCC
(12)
For example, a 68-μF capacitor with an 8-Ω speaker would attenuate low frequencies below 293 Hz. The BTL
configuration cancels the DC offsets, which eliminates the need for the blocking capacitors. Low-frequency
performance is then limited only by the input network and speaker response. Cost and PCB space are also
minimized by eliminating the bulky coupling capacitor.

Increasing power to the load does carry a penalty of increased internal power dissipation. The increased
dissipation is understandable considering that the BTL configuration produces 4× the output power of the SE
configuration.
9.4 Device Functional Modes
9.4.1 Summing Input Signals With The TPA6205A1
Most wireless phones or PDAs need to sum signals at the audio power amplifier or just have two signal sources
that need separate gain. The TPA6205A1 makes it easy to sum signals or use separate signal sources with
different gains. Many phones now use the same speaker for the earpiece and ringer, where the wireless phone
would require a much lower gain for the phone earpiece than for the ringer. PDAs and phones that have stereo
headphones require summing of the right and left channels to output the stereo signal to the mono speaker.
9.4.1.1 Summing Two Differential Input Signals
Two extra resistors are needed for summing differential signals (a total of 10 components). The gain for each
input source can be set independently (see Equation 13 and Equation 14, and Figure 30).

9.4.1.2 Summing a Differential Input Signal and a Single-Ended Input Signal
Figure 31 shows how to sum a differential input signal and a single-ended input signal. Ground noise can couple
in through IN+ with this method. It is better to use differential inputs. To assure that each input is balanced, the
single-ended input must be driven by a low-impedance source even if the input is not in use. Both input nodes
must see the same impedance for optimum performance, thus the use of RP and CP.

Four resistors and three capacitors are needed for summing single-ended input signals. The gain and corner

needed on the IN+ terminal to match the impedance on the IN- terminal. The single-ended inputs must be driven

The TPA6205A1 can be put in shutdown mode when asserting SHUTDOWN pin to a logic LOW. While in
shutdown mode, the device output stage is turned off, making the current consumption very low. The device exits
shutdown mode when a HIGH logic level is applied to SHUTDOWN pin. SHUTDOWN pin is 1.8-V compatible.

10.2.1.2.1.1 Resistors (RF and RI)
The input (RI) and feedback resistors (RF) set the gain of the amplifier according to Equation 23.
Gain - RF / RI
(23)
RF and RI should range from 1 kΩ to 100 kΩ. Most graphs were taken with RF = RI = 20 kΩ.
Resistor matching is very important in fully differential amplifiers. The balance of the output on the reference
voltage depends on matched ratios of the resistors. CMRR, PSRR, and the cancellation of the second harmonic
distortion diminishes if resistor mismatch occurs. Therefore, it is recommended to use 1% tolerance resistors or
better to keep the performance optimized.
10.2.1.2.1.2 Bypass Capacitor (CBYPASS) and Start-Up Time
The internal voltage divider at the BYPASS pin of this device sets a mid-supply voltage for internal references
and sets the output common mode voltage to VDD/2. Adding a capacitor to this pin filters any noise into this pin
and increases the kSVR. C(BYPASS)also determines the rise time of VO+ and VO– when the device is taken out of
shutdown. The larger the capacitor, the slower the rise time. Although the output rise time depends on the
bypass capacitor value, the device passes audio 4 μs after taken out of shutdown and the gain is slowly ramped
up based on C(BYPASS)
.
To minimize pops and clicks, design the circuit so the impedance (resistance and capacitance) detected by both
inputs, IN+ and IN–, is equal.
10.2.1.2.1.3 Input Capacitor (CI)
The TPA6205A1 does not require input coupling capacitors if using a differential input source that is biased from
0.5 V to VDD – 0.8 V. Use 1% tolerance or better gain-setting resistors if not using input coupling capacitors.
In the single-ended input application an input capacitor, CI, is required to allow the amplifier to bias the input
signal to the proper DC level. In this case, CI and RI form a high-pass filter with the corner frequency determined
in Equation 24.

Figure 33. CI and RI High-Pass Filter Cutoff Frequency
The value of CI is important to consider as it directly affects the bass (low frequency) performance of the circuit.
Consider the example where RI is 10 kΩ and the specification calls for a flat bass response down to 100 Hz.
Equation 24 is reconfigured as Equation 25.

CI =
2pRIfc
(25)
In this example, CI is 0.16 μF, so one would likely choose a value in the range of 0.22 μF to 0.47 μF. A further
consideration for this capacitor is the leakage path from the input source through the input network
(RI , CI) and the feedback resistor (RF ) to the load. This leakage current creates a DC offset voltage at the input
to the amplifier that reduces useful headroom, especially in high gain applications. For this reason, a ceramic
capacitor is the best choice. When polarized capacitors are used, the positive side of the capacitor should face
the amplifier input in most applications, as the dc level there is held at VDD/2, which is likely higher than the
source dc level. It is important to confirm the capacitor polarity in the application.
10.2.1.2.1.4 Decoupling Capacitor (CS)
The TPA6205A1 is a high-performance CMOS audio amplifier that requires adequate power supply decoupling to
ensure the output total harmonic distortion (THD) is as low as possible. Power supply decoupling also prevents
oscillations for long lead lengths between the amplifier and the speaker. For higher frequency transients, spikes,
or digital hash on the line, a good low equivalent-series-resistance (ESR) ceramic capacitor, typically 0.1 μF to 1
μF, placed as close as possible to the device VDD lead works best. For filtering lower frequency noise signals, a
10-μF or greater capacitor placed near the audio power amplifier also helps, but is not required in most
applications because of the high PSRR of this device.
10.2.1.2.2 Using Low-ESR Capacitors
Low-ESR capacitors are recommended throughout this applications section. A real (as opposed to ideal)
capacitor can be modeled simply as a resistor in series with an ideal capacitor. The voltage drop across this
resistor minimizes the beneficial effects of the capacitor in the circuit. The lower the equivalent value of this
resistance the more the real capacitor behaves like an ideal capacitor.

11 Power Supply Recommendations
The TPA6205A1 is designed to operate from an input voltage supply range between 2.5-V and 5.5-V. Therefore,
the output voltage range of power supply should be within this range and well regulated. The current capability of
upper power should not exceed the maximum current limit of the power switch.
11.1 Power Supply Decoupling Capacitors
The TPA6205A1 requires adequate power supply decoupling to ensure a high efficiency operation with low total
harmonic distortion (THD). Place a low equivalent-series-resistance (ESR) ceramic capacitor, typically 0.1 μF,
within 2 mm of the VDD pin. This choice of capacitor and placement helps with higher frequency transients,
spikes, or digital hash on the line. In addition to the 0.1 μF ceramic capacitor, is recommended to place a 2.2 μF
to 10 μF capacitor on the VDD supply trace. This larger capacitor acts as a charge reservoir, providing energy
faster than the board supply, thus helping to prevent any drop in the supply voltage.

12 Layout
12.1 Layout Guidelines
Placing the decoupling capacitors as close as possible to the device is important for the efficiency of the class-D
amplifier. Any resistance or inductance in the trace between the device and the capacitor can cause a loss in
efficiency.
For the DRB (QFN/SON) and DGN (MSOP) to presence of voids within the exposed thermal pad
interconnection. Total elimination is difficult, but the design of the exposed pad stencil is key. The stencil design
proposed in the Texas Instruments application note QFN/SON PCB Attachment (SLUA271) enables out-gassing
of the solder paste during reflow as well as regulating the finished solder thickness. Typically the solder paste
coverage is approximately 50% of the pad area.
In making the pad size for the BGA balls, it is recommended that the layout use soldermask-defined (SMD) land.
With this method, the copper pad is made larger than the desired land area, and the opening size is defined by
the opening in the solder mask material. The advantages normally associated with this technique include more
closely controlled size and better copper adhesion to the laminate. Increased copper also increases the thermal
performance of the IC. Better size control is the result of photo imaging the stencils for masks. Small plated vias
should be placed near the center ball connecting ball B2 to the ground plane. Added plated vias and ground
plane act as a heatsink and increase the thermal performance of the device. Figure 38 shows the appropriate
diameters for a 2 mm × 2 mm MicroStar Junior™ BGA layout.
It is very important to keep the TPA6205A1 external components very close to the TPA6205A1 to limit noise
pickup. The TPA6205A1 layout is shown in the next section as a layout example.
