CAPLESS 2Vrms AUDIO LINE DRIVER WITH ADJUSTABLE GAIN

DESCRIPTION

The UTC ALDR605 is a 2Vrms pop/click-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.

The UTC ALDR605 is capable of driving 2Vrms into a 2.5kΩ

load with 3.3V supply voltage. The device has single input and

uses external gain setting resistors that supports a gain range of

±1V/V to ±10V/V. The ALDR605 has build-in shutdown control for

pop/click-free on/off control.
