AD1994 Datasheet Audio Switching Amplifier

Manufacturer: Analog Devices

General Description

The AD1994 is a 2-channel, bridge tied load (BTL), switching audio power amplifier with integrated Σ-Δ modulator.

The modulator accepts a single-ended, analog input signal and converts it to a switching waveform to drive speakers directly.

One of the two modulators can control both output stages providing twice the current and almost twice the efficiency for single-channel applications.
