AK4213
Audio Subsystem with 1.6W Mono SPK-Amp and Stereo Cap-less HP-Amp
The AK4213 is an audio mono class-D speaker amplifier with stereo cap-less headphone amplifier. The AK4213 features analog mixing circuit that allow easy interfacing in mobile phone and portable A/V player designs. The input circuit supports both of single-ended and differential modes, and headphone supports stereo and mono modes. The speaker amplifier includes ALC (Automatic Level Control) circuit which is able to stabilize each output sound levels. The AK4213 is available in CSP package (3.0mm x 3.0mm), utilizing less board space than competitive offerings.
