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).
