GENERAL DESCRIPTION: The AD199x is a two channel Bridge Tied Load (BTL)   switching audio power amplifier with integrated ∑∆ modulator.   The modulator accepts a 1Vrms input signal (maximum power)   and generates a switching waveform to drive speakers directly.   One of the two modulators can control both output stages   providing twice the current for single-channel applications. A digital, microcontroller-compatible interface provides control of  reset, mute and PGA gain as well as output signals for thermal  and over-current error conditions. The output stage can operate   from supply voltages ranging from 8V to 20V. The analog   modulator and digital logic operate from a 5V supply.  AD1990: 5Wx2 (10Wx1)  AD1992: 10Wx2 (20Wx1)  AD1994: 25Wx2 (50Wx1)  AD1996: 40Wx2 (80Wx1)  FEATURES: Integrated Stereo Modulator & Power Stage  0.005% THD+N  101.5dB Dynamic Range  PSRR >...
