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 2.5k?
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.
FEATURES
* Integrated Charge pump generates negative supply rail
* Provides flat frequency response from DC to 20kHz
* Pop-Free under-voltage protection
* Low noise and THD Typical THD+N = 0.001% (f =1kHz)
* 2VRMS output voltage into 2.5k? load with 3.3V supply voltage
* 3VRMS output voltage into 2.5k? load with 5V supply voltage
