CAPLESS 2 VRMS TO 3 VRMS LINE DRIVER WITH ADJUSTABLE GAIN

DESCRIPTION

The UTC ALDR8905 is a 2VRMS to 3VRMS 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 ALDR8905 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 ALDR8905 has build-in shutdown control

for pop/click-free on/off control.
