The AD1994 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. One of the two modulators can control both output stages providing twice the current and almost twice the efficiency for single-channel applications. Both modulators can also control external power devices for arbitrarily high output power. 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.
