Overview
ES8323 Low Power Stereo Audio CODEC With Headphone Amplifier GENERAL DESCRIPTION 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.
