DESCRIPTION

The DRV602PW is a 3Vrms pop-free stereo line

driver designed to allow the removal of the output

dc-blocking capacitors for reduced component count

and cost. The device is ideal for single supply

electronics where size and cost are critical design

parameters.

Designed using TI's patented DirectPath?

technology, the DRV602 is capable of driving 3Vrms

into a 2.5kΩ load with 5V supply voltage. The device

has differential inputs and uses external gain setting

resistors, that supports a gain range of ±1V/V to

±10V/V. The use of external gain resistors also allows

the implementation of a 2nd order low pass filter to

compliment DAC's and SOC converters. The line

output of the DRV602 has ±8kV IEC ESD protection.

The DRV602 (referred to as the '602) has built-in

shutdown control for pop-free on/off control.

Using the DRV602 in audio products can reduce

component count compared to traditional methods of

generating a 3Vrms output. The DRV602 doesn't

require a power supply greater than 5V to generate

its 8.5VPP output, nor does it require a split rail power

supply. The DRV602 integrates its own charge pump

to generate a negative supply rail that provides a

clean, pop-free ground biased 3Vrms output.

The DRV602 is available in a 14 pin TSSOP

package.

If higher SNR, trimmed DC-offset and external

undervoltage-mute functions are beneficial in the

application, TI recommends the footprint compatible DRV603 (SLOS617).

(SLOS659).
