The AR7646 Touch Screen Controller IC is an advanced version of the
AR7643. The AR7646 is a 12-bit SAR analog-to-digital converter (ADC) with
SPI serial interface and low on-resistance drivers for 4-wire resistive touch
The AR7646 is a highly integrated controller for portable applications which
use 4-wire resistive touch panels such as PDAs, portable instruments, cellular
phones, etc. The AR7646 contains all the analog and digital circuitry
necessary to complete a pen request. The AR7646 features temperature,
battery monitor and touch-pressure measurements and also provides an
internal 2.5 V reference that may be turned ON or OFF independently of the
The AR7646 consumes only 405 mW (internal reference OFF) at a 125 KHz
sample rate and a 2.7 V supply and consumes power less than 2.7 mW in
shutdown mode. The AR7646 is guaranteed down to 2.2 V supply. The
AR7646 is provided in a very small 16-lead SSOP package and is guaranteed
over the temperature range from 40 to +85°C.
