ADAU1590 - Class-D Audio Power Amplifier

Description

The ADAU1590 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.

Class-D Audio Power Amplifier ADAU1590 FEATURES Integrated stereo modulator and power stage 0.005% THD + N 101 dB dynamic range PSRR >55 dB RDS-ON < 0.3 Ω (per transistor) Efficiency > 90% (8 Ω) EMI-optimized modulator On/off-mute pop-noise suppression Short-circuit protection Overtemperature protection GENERAL DESCRIPTION The ADAU1590 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 15 V.
