PA5331
Low Power 24-Bit, Stereo Audio CODEC
With Headphone Amplifier
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.
