1. Product Overview
Stereo analog-to-digital converter (ADC)
Dual analog or digital mic input
Dual mic bias generators
Dual digital-to-analog converters (DACs) ground-centered headphone amp.
One serial port with asynchronous sample rate converters
Digital audio mixing for all paths
Fully custom 5 Band BiQuad Equalizer for record or playback path
2. Applications
Digital Mic, Wireless IP camera, Mobile Internet Devices, Car Driving Camera, Digital Headphone
3. Features
Native (no PLL required) support for 6/6.144/12/12.288 MHz master clock rates
High-efficiency power management reduces power consumption. Step down charge pump provides low supply voltage and negative voltage for HP amplifier
