General Description

The M4670 is a fully integrated single-supply, high-efficiency Class D switching audio amplifier, and it can provide 3W of output power.

Containing adjustable output gain chip with micro-power shutdown mode, the M4670 has innovative modulation schemes that eliminate the output filter wave devices and thus reduces the requirement of external components helping to streamline the circuit design and reduce board area.

By using delta-sigma modulation technique which handles incoming analog signal, the M4670 can reduce the output noise and total harmonic distortion.
