Low Power Stereo Audio CODEC
With Headphone Amplifier
Revision 1.0 April 2011
1 ES8323
GENERAL DESCRIPTION
FEATURES
ES8323 is a high performance, low power and low cost audio CODEC. It consists of 2-ch ADC, 2-ch DAC, microphone amplifier, headphone amplifier, digital sound effects, and analog mixing and gain functions.
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.
