Low Power Stereo Audio CODEC

With Headphone Amplifier

ANALOG PRODUCTS DIVISION

FEATURES

GENERAL DESCRIPTION

DAC

24-bit, 8 kHz to 96 kHz sampling frequency

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.

96 dB dynamic range, 96 dB signal to noise ratio, -83 dB

THD+N

40 mW headphone amplifier, pop noise free, capless

option

Stereo enhancement

The device uses advanced multi-bit delta-sigma modulation

technique to convert data between digital and analog.

Bass and Treble adjustments

Various analog output mixing and gains

The multi-bit delta-sigma modulators make the device with low

sensitivity to clock jitter and low out of band noise.

Low Power

1.8V to 3.3V operation

7 mW playback

System

I²C or SPI uC interface

256Fs, 384Fs, USB 12 MHz or 24 MHz

Master or slave serial port
