AK7770EQ Datasheet Audio DSP

Manufacturer: AKM (Asahi Kasei Microdevices)

General Description

The AK7770 is a digital signal processor with an integrated 4-channel audio ADC and a 6-channel audio DAC, as well as an S/PDIF transmitter.

It utilizes an enhanced dual bit architecture that results in wide dynamic range for the ADC, and the advanced multi-bit architecture of the DAC enables wide dynamic range and low out-of-band noise.

Two sample-rate converters are integrated, allowing for operation at 48kHz sampling rate with input rates of 32kHz, 44.1kHz, or 48kHz.
