Class-D Audio Power Amplifier

ADAU1592

FEATURES

GENERAL DESCRIPTION

Integrated stereo modulator and power stage

0.005% THD + N

101 dB dynamic range

PSRR > 65 dB

The ADAU1592 is a 2-channel, bridge-tied load (BTL)

switching audio power amplifier with an integrated Σ-Δ

modulator.

The modulator accepts an analog input signal and generates

a switching output to drive speakers directly. A digital,

microcontroller-compatible interface provides control of reset,

mute and PGA gain as well as output signals for thermal and

overcurrent error conditions. The output stage can operate

from supply voltages ranging from 9 V to 18 V. The analog

modulator and digital logic operate from a 3.3 V supply.

_DS-ON< 0.3 Ω (per transistor)

Efficiency > 90% (8 Ω)

EMI-optimized modulator

On/off-mute pop-noise suppression

Short-circuit protection

Overtemperature protection

APPLICATIONS

Flat panel televisions

PC audio systems
