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.
