DATASHEET  
PORTABLE CONSUMER CODEC  
LOW-POWER, HIGH-FIDELITY INTEGRATED CODEC  
ACS422Mx68  
The ACS422Mx68 is a low-power, high-fidelity integrated  
CODEC targeted at portable applications such as tablet  
computers, personal navigation devices, portable  
FEATURES  
High fidelity 24-bit stereo CODEC  
DAC 102dB SNR; THD+N better than -82dB  
projectors and speaker docks. In addition to a high-fidelity  
ADC 90dB SNR, THD + N better than -80dB  
TM  
low-power CODEC, the device integrates a MONO DDX  
Built in audio controls and processing  
Class D speaker amplifier and a true cap-less headphone  
amplifier. Beyond high-fidelity for portable systems, the  
device offers an enriched “audio presence” through built-in  
audio processing capability.  
3D stereo enhancement  
Dual (cascaded) stereo 6-band parametric equalizers  
Programmable Compressor/Limiter/Expander  
Psychoacoustic Bass and Treble enhancement  
processing

Tri-state DDXTM Class D achieves low EMI and high  
efficiency  
>80% efficiency at 1W  
Spread spectrum support for reduced EMI output power  
mode  
Anti-Pop circuitry  
On-chip true cap-less headphone driver  
35 mW output power (16)  
Charge-pump allows true ground centered outputs  
SNR of 102dB  
I2S data interface  
Microphone/line-in interface  
Analog microphone or line-in inputs  
Digital microphone (ACS422MD68)  
Automatic level control  
On-chip low-jitter PLL for audio timing  
Low power with built in power management  
1.7 V CODEC supports 1Vrms  
Very low standby and no-signal power consumption  
1.8V digital / 1.7V analog supply for low power
