GENERAL DESCRIPTION
The AD199x is a two channel Bridge Tied Load (BTL)
switching audio power amplifier with integrated
鈭?/div>

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)
