Analog Devices AD1996

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. The output stage can operate from supply voltages ranging from 8V to 20V.

GENERAL DESCRIPTION

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 analog modulator and digital logic operate from a 5V supply. AD1990: 5Wx2 (10Wx1) AD1992: 10Wx2 (20Wx1) AD1994: 25Wx2 (50Wx1) AD1996: 40Wx2 (80Wx1)
