　　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 error conditions. The output stage can operate
　　from supply voltages ranging from 9 V to 15 V. The analog
　　modulator and digital logic operate from a 3.3 V supply.
