ACM8625P - Digital Input Class-D Audio Amplifier

Datasheet Summary

Description

ACM8625P is a fully integrated, high efficiency, stereo ClassD audio amplifier with digital inputs.

The application circuit requires few passives components to operate with 4.5V to 21V PVDD supply, 3.3V DVDD supply.

It can drive 2×33W output power into BTL 6Ω and 1×51W into PBTL 4Ω@1% THD+N.

Features

  • Flexible Power Supply Configurations - PVDD: 4.5V to 21V - DVDD and I/O: 3.3V.
  • Various output configurations - 2×33W, Stereo mode (6Ω, 21V, THD+N = 1%) - 1×51W, Mono mode (4Ω, 21V, THD+N = 1%).
  • Excellent Audio Performance - THD+N ≤ 0.04% at 1W, 1kHz, PVDD = 12V - 112 dB A-weighted signal-to-noise ratio (SNR) - Idle switching A-weighted noise ≤ 35 - 18 mA low quiescent current - 90% efficiency into 6Ω load at 12V.
  • Configurable digital audio interface - I C control with up to.
