DIRECT 2-VRMS AUDIO LINE

DRIVER WITH ADJUSTABLE

GAIN



DESCRIPTION

The UTC PA3632 is a pop-free stereo line driver with the integrated

charge pump generating the negative supply rail which allows the

removal of the output DC-blocking capacitors. The UTC PA3632

provides a clean, pop-free ground-biased audio signal. The UTC

PA3632 is capable of driving 2VRMS into a 10kΩ load with 3.3V supply

voltage. The device has differential inputs and uses external resistors

for flexible gain setting. Gain can be configured individually for each

channel.

The UTC PA3632 has built-in active-mute control for pop-free audio

on/off control. The UTC PA3632 has an external under-voltage detector

that mutes the output when monitored voltage drop below set value.

The device has differential inputs and uses external gain-setting

resistors to support a gain range of ±1V/V to ±10V/V, and gain can be

configured individually for each channel. Line outputs have ±8-Kv

(HBM) IEC ESD protection, requiring just a simple resistor-capacitor

ESD protection circuit.

Using the UTC PA3632 in audio products can reduce component

count considerably compared to traditional headphone amplifiers.
