ADAU1592: Class-D Audio Power Amplifier
Product Description
The ADAU1592 is a 2-channel, bridge-tied load (BTL) switching audio power amplifier with an integrated Σ-Δ modulator.
The modulator accepts an analog input signal and generates a switching output to drive speakers directly. A digital, microcontroller-compatible interface provides control of reset, mute, and PGA gain as well as output signals for thermal and overcurrent error conditions. The output stage can operate from supply voltages ranging from 9 V to 18 V. The analog modulator and digital logic operate from a 3.3 V supply.
