GENERAL DESCRIPTION
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-compatible interface provides control of reset, mute and PGA gain as well as output signals for thermal and overcurrent err...
