PA5155
Low Power Stereo Audio CODEC
With Headphone Amplifier
GENERAL DESCRIPTION
PA5155 is a high performance, low power and low cost audio
DAC. It consists of 2-ch DAC, 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.
