AD1994 - Audio Switching Amplifier

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.

Features

  • Integrated stereo modulator and power stage 65 dB On-off-mute pop noise suppression EMI optimized modulator Short-circuit protection Overtemperature protection Low cost DMOS process.
