GENERAL DESCRIPTION
The AD1992 is a 2-channel, bridge tied load (BTL), switching audio power amplifier with integrated - modulator.

The modulator accepts a single-ended, analog input signal and converts it to a switching waveform to drive speakers directly. A digital, microprocessor-compatible interface provides control of reset, mute, and PGA gain, as well as feedback signals for thermal and overcurrent error conditions. The output stage can operate over a power supply voltages range of 8 V to 20 V. The analog modulator and digital logic operate from a 5 V supply.
