Touch Screen Controller
Description
The APT7843 Touch Screen Controller IC provides all
the screen drive , A/D converter and control circuits
to easily interface to 4 wire resistive touch screen.
The IC continually monitors the screen waiting for a
touch. When the screen touched , the IC performs
A/D converter to determine the location of touch.
Also , this device has 2 auxiliary input to A/D con-
verter , allowing for the measurement of other inputs
such as battery voltage.
