General Description

The ZT2046 is a 4‐wire touch screen controller with programmable 8‐bit or 12‐bit successive approximation converter, synchronous serial interface and low on‐resistance switches.

The ZT2046 operates from 2.2V to 5.25V and fea‐ tures touch pressure measurement, battery measurement, and temperature measurement.

The ZT2046 also has an internal 2.5V reference that can be used for the auxiliary analog input, battery voltage detection, and temperature measurement modes.
