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 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
APPLICATIONS
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.
