[ASAHI KASEI] [AK7740ET] AK7740ET 24bit 2ch ADC + 24bit 4ch DAC with Audio DSP 1. General Description 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. This device includes 72kbits of SRAM audio delay that is suitable for simulated sound fields. The DSP is optimized for audio signal processing. The design allows up to 512 execution lines per audio sample cycle, with multiple functions per line.
