ADAU1590 Overview
The ADAU1590 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-patible interface provides control of reset, mute and PGA gain as well as output signals for thermal and overcurrent error conditions.
