Dual BTL 20W Audio Power Amplifier

Circuit Diagram:

5Wx2 10Wx2 25Wx2 40Wx2 Dual BTL class-D power audio amplifier AD199x

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.
