AK4223  
6:2 Audio Switch and 6:2 Video Switch  
GENERAL DESCRIPTION  
The AK4223 is an AV switch with 6:2 audio and 6:2 video switches. High performances with low power  
consumption are achieved by CMOS process. Integrated differential input circuits in audio and video  
blocks can separate the external ground noise. In audio block, a differential input circuit, audio LPF and  
0dB/-6dB gain amplifier are integrated eliminating the needs for external LPF for audio outputs. In video  
block, an input clamp circuit, 6dB amplifier and video driver are integrated, and they also eliminate the  
need for external circuits. The AK4223 is offered in a space saving small 48-pin LQFP package, ideal for  
car navigation applications.
