GENERAL DESCRIPTION
The AK4673 is a stereo CODEC with a built-in Microphone-Amplifier, Headphone-Amplifier and Touch
Screen Controller (TSC) which includes the SAR type ADC. The AK4673 features analog mixing circuits,
PLL and a 4-wire resistive touch screen I/F that allows easy interfacing in mobile phone and portable A/V
player designs. The AK4673 is available in a 57pin BGA package, utilizing less board space than
competitive offerings.
