AK7740ET Overview
The AK7740 is a highly integrated audio processing IC, including four 24-bit output D/A channels, a stereo 24-bit input A/D, and an audio DSP. High quality analog output performance is provided by the quad DAC with 97dB dynamic range, and the stereo ADC with 98dB dynamic range. The converters support sampling frequencies from 32kHz to 48kHz.
