GENERAL DESCRIPTION

The PA5331 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 PA5331 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.
