General Description
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.
