TOUCH SCREEN DRIVER 4-WIRE RESISTANCE, LOW-VOLTAGE I/O INTERFACE
DESCRIPTION
Features
The A8946 is a 4-wire touch screen driver which supports a low-voltage I/O interface from 1.5V to 5.25V.
1.5V to 5.25V digital I/O 2.2V to 5.25V operation
The A8946 has an on-chip 2.5V reference that can
4-wire I/F be used for the auxiliary input, battery monitor, and
Internal 2.5V reference temperature measurement modes. The reference can also be powered down when not used to
Direct battery measurement(0V to 6V) conserve power. The internal reference operates
Programmable 8 or 12 bit Resolution down to 2.7V supply voltage, while monitoring the...
