Description
A standby mode function (active low) keeps the
current consumption down to 1 μA typical.
The TS2007FC is a class D power audio
amplifier. Able to drive up to 1.4 W into an 8 Ω
load at 5 V, it achieves better efficiency than
typical class AB audio power amplifiers.
The TS2007FC is available in a 9-bump flip-chip
lead-free package.
This device can switch between two gain settings,
6 dB or 12 dB via a logic signal on the gain select
pin. Pop and click reduction circuitry provides low
on/off switch noise and allows the device to start
within 1 ms typically.

Output short circuit protection (7)
1. All voltage values are measured with respect to the ground pin.
2. The magnitude of input signal must never exceed VCC + 0.3 V / GND - 0.3 V
3. The device is protected in case of over temperature by a thermal shutdown active @ 150° C.
4. Exceeding the power derating curves during a long period provokes abnormal operating conditions.
5. Human body model: 100 pF discharged through a 1.5 kΩ resistor between two pins of the device, done for
all couples of pin combinations with other pins floating.
6. Machine model: a 200 pF cap is charged to the specified voltage, then discharged directly between two
pins of the device with no external series resistor (internal resistor < 5 Ω), done for all couples of pin
combinations with other pins floating.
7. Implemented short-circuit protection protects the amplifier against damage by short-circuit between
positive and negative outputs and between outputs and ground.

Application information
4.1
Differential configuration principle
The TS2007 is a monolithic fully-differential input/output class D power amplifier. The
TS2007 includes a common-mode feedback loop that controls the output bias value to
average it at V /2 in the range of DC common mode input voltage. This allows the device
CC
to always have a maximum output voltage swing, and by consequence, maximize the output
power. In addition, as the load is connected differentially compared to a single-ended
topology, the output is four times higher for the same power supply voltage.
A fully-differential amplifier has the following advantages.
●
●
●
High PSRR (power supply rejection ratio).
High CMRR (common mode noise rejection).
Virtually zero pop without additional circuitry, giving a faster start-up time than
conventional single-ended input amplifiers.
●
●
Easy interfacing with differential output audio DACs.
No input coupling capacitors required since there is a common mode feedback loop.
4.2
Gain settings
In the flat region of the frequency-response curve (no input coupling capacitor or internal
feedback loop + load effect), the differential gain can be set to either 6 or 12 dB depending
on the logic level of the GS pin.
Table 11. GS pin gains
GS pin
Gain (dB)
Gain (V/V)
1
0
6 dB
2
4
12 dB
Note:
Between the GS pin and V there is an internal 300 kΩ resistor. When the pin is floating
CC
the gain is 6 dB. In standby mode, this internal resistor is disconnected (HiZ input).
4.3
Common mode feedback loop limitations
As explained previously, the common mode feedback loop allows the output DC bias voltage
to be averaged at V /2 for any DC common mode bias input voltage.
CC
Due to the V limitation of the input stage (see Table 2: Operating conditions), the common
icm
mode feedback loop can fulfill its role only within the defined range.

Low frequency response
If a low frequency bandwidth limitation is required, it is possible to use input coupling
capacitors. In the low frequency region, the input coupling capacitor C has a greater effect.

Circuit decoupling
A power supply capacitor, referred to as C , is needed to correctly bypass the TS2007.
S
The TS2007 has a typical switching frequency of 280 kHz and output fall and rise time of
less than or equal to 5 ns. Due to these very fast transients, careful decoupling is
mandatory.
A 1 µF ceramic capacitor is enough, but it must be located very close to the TS2007 in order
to avoid any extra parasitic inductance created by a long track wire. Parasitic loop
inductance, in relation with di/dt, introduces overvoltage that decreases the global efficiency
of the device and may cause, if this parasitic inductance is too high, a TS2007 breakdown.
For filtering low frequency noise signals on the power line, it is recommended to use a
capacitor C of at least 1 µF.
S
In addition, even if a ceramic capacitor has an adequate high frequency ESR (equivalent
series resistance) value, its current capability is also important. A 0603 size is a good
compromise, particularly when a 4 Ω load is used.
Another important parameter is the rated voltage of the capacitor. A 1 µF/6.3 V capacitor
used at 5 V, loses about 50% of its value: with a power supply voltage of 5 V, the decoupling
value, instead of 1 µF, could be reduced to 0.5 µF. As C has particular influence on the
S
THD+N in the medium to high frequency region, this capacitor variation becomes decisive.
In addition, less decoupling means higher overshoots which can be problematic if they reach
the power supply AMR value (6 V).
4.6
Wake-up time (twu)
When the standby is released to set the device ON, there is a wait of 1 ms typically. The
TS2007 has an internal digital delay that mutes the outputs and releases them after this
time in order to avoid any pop noise.
Note:
The gain increases smoothly (see Figure 42 and Figure 43) from the mute to the gain
selected by the GS pin (Section 4.2).

4.7
Shutdown time
When the standby command is set to high, the time required to put the two output stages
into high impedance and to put the internal circuitry in shutdown mode, is typically 1 ms.
This time is used to decrease the gain and avoid any pop noise during shutdown.
Note:
The gain decreases smoothly until the outputs are muted (see Figure 42 and Figure 43).
4.8
Consumption in shutdown mode
Between the shutdown pin and GND there is an internal 300 kΩresistor. This resistor forces
the TS2007 to be in shutdown when the shutdown input is left floating.
However, this resistor also introduces additional shutdown power consumption if the
shutdown pin voltage does not equal 0 V. This extra current is provided by the device that
drives the standby pin of the amplifier.
Referring to Table 2: Operating conditions on page 4, with a 0.4 V shutdown voltage pin for
example, you must add 0.4 V/300 k = 1.3 µA in typical (0.4 V/273 k = 1.46 µA maximum) to
the shutdown current specified in Table 5 to Table 9.
4.9
Single-ended input configuration
It is possible to use the TS2007 in a single-ended input configuration. However, input
coupling capacitors are needed in this configuration. The following schematic diagram
shows a typical single-ended input application.

Output filter considerations
The TS2007 is designed to operate without an output filter. However, due to very sharp
transients on the TS2007 output, EMI radiated emissions may cause some standard
compliance issues.
These EMI standard compliance issues can appear if the distance between the TS2007
outputs and loudspeaker terminal are long (typically more than 50 mm, or 100 mm in both
directions). As the PCB layout and internal equipment device are different for each
configuration, it is difficult to provide a one-size-fits-all solution.
However, to decrease the probability of EMI issues, there are several simple rules to follow.
●
Reduce, as much as possible, the distance between the TS2007 output pins and the
speaker terminals.
●
●
Use a ground plane for shielding sensitive wires.
Place, as close as possible to the TS2007 and in series with each output, a ferrite bead
with a rated current of minimum 2.5 A and impedance greater than 50 Ω at frequencies
above 30 MHz.
●
Allow extra footprint to place, if necessary, a capacitor to short perturbations to ground
(Figure 45).

In the case where the distance between the TS2007 output and the speaker terminals is too
long, it is possible to have low frequency EMI issues due to the fact that the typical operating
PWM frequency is 280 kHz and fall and rise time of the output signal is less than or equal to
5 ns. In this configuration, it is necessary to use the output filter represented in Figure 46 on
page 24, that consists of L1, C1, L2 and C2 as close as possible to the TS2007 outputs.
When an output filter is used and there exists a possibility to disconnect a load, it is
recommended to use an RC network that consists of C3 and R as shown in Figure 46 on
page 24. In this case, when the output filter is connected without any load, the filter acts like
a short circuit for input frequencies above 10 kHz. The RC network corrects frequency
response of the output filter and compensates this limitation.

Short-circuit protection
The TS2007 includes an output short-circuit protection. This protection prevents the device
from being damaged if there are fault conditions on the amplifier outputs.
When a channel is in operating mode and a short-circuit occurs directly between two
outputs (Out+ and Out-) or between an output and ground (Out+ and GND or Out- and
GND), the short-circuit protection detects this situation and puts the amplifier into standby.
To put the amplifier back into operating mode, put the standby pin to logical LO and then to
logical HI.
Thermal shutdown
The TS2007 device has an internal thermal shutdown protection in the event of extreme
temperatures to protect the device from overheating. Thermal shutdown is active when the
device reaches 150°C. When the temperature decreases to safe levels, the circuit switches
back to normal operation.
