FEATURES
DESCRIPTION
The DRV612 is a single-ended, 2-Vrms stereo line
driver designed to reduce component count, board
space and cost. It is ideal for single-supply
electronics where size and cost are critical design
parameters.

Low Noise and THD
The DRV612 does not require a power supply greater
than 3.3 V to generate its 5.6-VPP output, nor does it
require a split-rail power supply.

Designed using TI’s patented DirectPath technology,
which integrates a charge pump to generate a
negative supply rail that provides a clean, pop-free
ground-biased output. The DRV612 is capable of

technology also allows the removal of the costly
output dc-blocking capacitors.
Single-Ended Input and Output
Programmable Gain Select Reduces
Component Count
The device has fixed-gain single-ended inputs with a
gain-select pin. Using a single resistor on this pin, the
designer can choose from 13 internal programmable
gain settings to match the line driver with the codec
output level. It also reduces the component count and
board space.

APPLICATION INFORMATION
LINE DRIVER AMPLIFIERS
Single-supply line-driver amplifiers typically require dc-blocking capacitors. The top drawing in Figure 8 illustrates
the conventional line-driver amplifier connection to the load and output signal.
DC blocking capacitors are often large in value, and a mute circuit is needed during power up to minimize click
and pop. The output capacitor and mute circuit consume PCB area and increase cost of assembly, and can
reduce the fidelity of the audio output signal.

Figure 8. Conventional and DirectPath Line Driver
The DirectPath amplifier architecture operates from a single supply but makes use of an internal charge pump to
provide a negative voltage rail.
Combining the user-provided positive rail and the negative rail generated by the IC, the device operates in what
is effectively a split supply mode.
The output voltages are now centered at zero volts with the capability to swing to the positive rail or negative rail.
Combining this with the built-in click- and pop-reduction circuit, the DirectPath amplifier requires no output
dc-blocking capacitors.
The bottom block diagram and waveform of Figure 8 illustrate the ground-referenced line-driver architecture. This
is the architecture of the DRV612.

COMPONENT SELECTION
Charge Pump Flying Capacitor and VSS Capacitor
The charge-pump flying capacitor serves to transfer charge during the generation of the negative supply voltage.
The VSS capacitor must be at least equal to the charge pump capacitor in order to allow maximum charge
transfer. Low-ESR capacitors are an ideal selection, and a value of 1 μF is typical.
Decoupling Capacitors
The DRV612 is a DirectPath line-driver amplifier that requires adequate power-supply decoupling to ensure that
the noise and total harmonic distortion (THD) are low. A good low equivalent-series-resistance (ESR) ceramic
capacitor, typically 1 μF, placed as close as possible to the device VDD lead works best. Placing this decoupling
capacitor close to the DRV612 is important for the performance of the amplifier. For filtering lower-frequency
noise signals, a 10-μF or greater capacitor placed near the audio power amplifier also helps, but it is not required
in most applications because of the high PSRR of this device.
Gain-Setting
The gain setting is programmed with the GAIN pin. Gain setting is latched durning power on. Table 1 lists the
gain settings.
NOTE: If gain pin is left unconnected (open) default gain of –2× is selected.

Input-Blocking Capacitors
DC input-blocking capacitors are required to be added in series with the audio signal into the input pins of the
DRV612. These capacitors block the dc portion of the audio source and allow the DRV612 inputs to be properly
biased to provide maximum performance. The input blocking capacitors also limit the dc gain to 1, limiting the
dc-offset voltage at the output.
These capacitors form a high-pass filter with the input resistor, RIN. The cutoff frequency is calculated using
Equation 1. For this calculation, the capacitance used is the input-blocking capacitor and the resistance is the
input resistor chosen from Table 2. Then the frequency and/or capacitance can be determined when one of the
two values is given.

For a fixed cutoff frequency of 2 Hz, the size of the input capacitance is shown in Table 2 with the capacitors
rounded up to nearest E6 values. For 20-Hz cutoff, simply divide the capacitor values with 10; e.g., for 1× gain,
150 nF is needed.

Pop-Free Power Up
Pop-free power up is ensured by keeping the MUTE pin low during power-supply ramp-up and -down. The pins
should be kept low until the input ac-coupling capacitors are fully charged before asserting the MUTE pin high,
this way proper pre-charge of the ac-coupling is performed and pop-less power up is achieved. Figure 9
illustrates the preferred sequence.

CAPACITIVE LOAD
The DRV612 has the ability to drive a high capacitive load up to 220 pF directly. Higher capacitive loads can be
accepted by adding a series resistor of 47 Ω or larger for the line driver output.
LAYOUT RECOMMENDATIONS
A proposed layout for the DRV612 can be seen in the DRV612EVM User's Guide (SLOU248), and the Gerber
files can be downloaded from http://focus.ti.com/docs/toolsw/folders/print/DRV612evm.html. To access this
information, open the DRV612 product folder and look in the Tools and Software folder.
Ground traces are recommended to be routed as a star ground to minimize hum interference. VDD, VSS
decoupling capacitors and the charge-pump capacitors should be connected with short traces.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
(3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
Important Information and Disclaimer:The information provided on this page represents TI's knowledge and belief as of the date that it is provided. TI bases its knowledge and belief on information
provided by third parties, and makes no representation or warranty as to the accuracy of such information. Efforts are underway to better integrate information from third parties. TI has taken and
