ES7322

ES7322 100dB, 24-Bit, 192 kHz Stereo Audio CODEC GENERAL DESCRIPTION ES7322 is a low cost high performance stereo audio CODEC. ES7322 performs stereo digital to analog conversion and analog to digital conversion continuously from 8 kHz to 200 kHz sampling frequency. ES7322 is ideal for high performance cost sensitive consumer audio applications. ES7322 can accept I²S, left justified and right justified serial audio data formats up to 24-bit word length. ADC and DAC operate on independent sampling frequencies and clocks. The device uses advanced multi-bit delta-sigma modulation technique to convert data between digital and analog. The multi-bit delta-sigma modulators make the device with low sensitivity to clock jitter and low out of band noise. ES7322 can operate either in the hardware mod or the software mode. In the hardware mode, pin M0, M1, M2 and M3 set the operation of the device. In the software mode, ES7322 provides SPI or 2-wire micro-controller interfaces to configure its ...
