AK4184

TSC with Keypad Scanner and GPIO Expander

GENERAL DESCRIPTION

The AK4184 is a 12-bit A/D converter witch operates 125kHz (max) sampling rate with a 4-wire resistive

touch screen controller (TSC), including low-on resistance switches, touch pressure measurement

capability, a maximum 6 x 5 keypad scanner, eight GPIO ports, and a PWM generator for LED contrast

control. The AK4184 operates down to a 2.5V supply voltage, and it tolerates digital I/O interface voltage

from 1.6V to AVDD in order to connect to low voltage controllers. The AK4184 supports SPI interface for

communication to a host controller. The AK4184 is available in a 41-pin BGA package and it operates over

a temperature range of -40°C to +85°C. The AK4184 is suitable for Cellular Phone, DSC, DVC, Smart

Phone and MP3 player application systems.
