[AK4961] AK4961 Low-Power CODEC with Audio/Voice DSP 1. General Description The AK4961 is four channels 24-bit ADC, stereo advanced 32-bit high sound quality audio DAC and stereo 24-bit DAC with a built-in microphone amplifier, mono receiver amplifier, ground-referenced headphone amplifier, lineout, and a high feature Audio/Voice DSP. The AK4961 features AKM’s DSP core that enables various kinds of voice processing such as voice wakeup, dual mic Tx noise suppression, Rx noise suppression, echo cancellation, and hands free functions. The AK4961 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. 2.
