[AK4962] AK4962 Low-Power CODEC with Audio/Voice DSP 1. General Description The AK4962 is four channels 32-bit ADC, monaural ADC, stereo advanced 32-bit high sound quality audio DAC and stereo 32-bit DAC with a built-in microphone amplifier, mono receiver amplifier, ground-referenced headphone amplifier, lineout, and a high feature Audio/Voice DSP. The AK4962 features AKM’s DSP core to deal with various kinds of voice processing features such as dual mic Tx noise suppression, Rx noise suppression, echo cancellation, and hands free functions. The AK4962 has five audio I/F and SLIMbus I/F to communicate with an Application processor, up to two Baseband processors, a Bluetooth module and a digital input class-D amplifier simultaneously, and mixes asynchronous signal with built-in SRCs. 1. 2. 2.
