The PA5388 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.
The PA5388 is pin to pin compatible to WM8988 except Pin9
ALRCK and Pin25 DACREF. See the Pin Configuration Table.
