ES8323

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.
