2-Vrms DirectPathLine Driver With Programmable-Fixed Gain  
Check for Samples: DRV612

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.

DirectPath  
Eliminates Pops/Clicks  
Eliminates Output DC-Blocking Capacitors  
3-V to 3.6-V Supply Voltage  
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.  
SNR > 105 dB at 1× Gain  
Typical Vn < 12 μVms 20 Hz20 kHz  
at 1× Gain  
Designed using TIs 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  
THD+N < 0.003% at 10-kΩ Load  
and 1× Gain  
2-Vrms Output Voltage Into 600-Ω Load  
driving  
2 Vms into a 600-Ω load. DirectPath  
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.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam  
during storage or handling to prevent electrostatic damage to the MOS gates.

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.

SLOS690B DECEMBER 2010REVISED APRIL 2011  
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 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.

FOOTPRINT COMPATIBLE WITH TPA6139A2  
The DRV612 stereo line driver is pin compatible with the headphone amplifier TPA6139A2. Therefore, a single  
PCB layout can be used with stuffing options for different board configurations.

(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.
