AD1996 - Class-D Audio Power Amplifier

General Description

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.

Preliminary Technical Data FEATURES Integrated Stereo Modulator & Power Stage 0.005% THD+N 101.5dB Dynamic Range PSRR > 65 dB RDS-ON < 0.3 Ω (per transistor) Efficiency > 80% @ 5W/6 Ω EMI Optimized Modulator On-Off-Mute Pop Noise Suppression Short Circuit Protection Over-Temperature Protection Low Cost DMOS Process Class-D Audio Power Amplifier AD1990/AD1992/AD1994/AD1996 GENERAL DESCRIPTION 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. One of the two modulators can control both output stages providing twice the current for single-channel applications.
