FEATURES

DESCRIPTION

•

DirectPath™

The DRV603PW is a 3-V_RMSpop-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.

technology, The DRV603 is capable of driving 3 V_rms

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

device has differential inputs and uses external

gain-setting resistors to support a gain range of ±1

V/V to ±10 V/V, and line outputs that have ±8 kV IEC

ESD protection. The DRV603 (occasionally referred

to as the ‘603) has built-in shutdown control for

pop-free on/off control. The DRV603 has an external

and internal undervoltage detector that mutes the

output.

External Undervoltage Mute

Using the DRV603 in audio products can reduce

component count considerably compared to

traditional methods of generating a 3-V_rmsoutput. The

DRV603 does not require a power supply greater

than 5 V to generate its 8.5-V_ppoutput, nor does it

require

a split-rail power supply. The DRV603

integrates its own charge pump to generate a

negative supply rail that provides a clean, pop-free

ground biased 3-V_rmsoutput.

The DRV603 is available in a 14-pin TSSOP.

If the low noise and trimmed dc-offset and external

undervoltage mute function are not beneficial in the

application, TI recommends the footprint compatible

DRV602.
