AN12906A is an input/output interface IC that has built-in audio capability. This IC integrates in a single chip configuration a speaker amplifier, headphone amplifier, microphone amplifier, AGC, microphone voltage supply and LPF. Power supply voltage for Speaker-drive can drive low-voltage of 1.8 voltage. AN12906A has the power-save function for each amplifier's.
The AN12906A audio interface IC integrates a speaker amplifier, headphone amplifier, microphone amplifier, AGC, microphone bias and low‑pass filter in a single QFN44 package. It operates from a 2.7 V‑4.2 V supply and includes power‑save modes for each amplifier.
Typical applications include IC recorders, PDAs, digital still cameras and other portable electronic equipment. The datasheet provides pin descriptions, absolute maximum ratings, recommended operating ranges and detailed electrical characteristics.
