Overview

Audio Switching Amplifier AD1990 FEATURES Integrated stereo modulator and power stage <0.
002% THD + N 101 dB dynamic range (A-weighted) 2 × 5 W output power (4 Ω, <0.
01% THD + N) RDS-ON < 0.
3 Ω (per transistor) PSRR > 65 dB On-off-mute pop noise suppression EMI optimized modulator Short-circuit protection Overtemperature protection Low cost DMOS process GENERAL DESCRIPTION The AD1990 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.
A digital, microprocessor-compatible interface provides control of reset, mute, and...
