Hot-selling and scarce AK4181AVT TOUCH SCREEN CONTROLLER TSSOP16

Product Descriptions

Ak4181a is a 4-wire touch screen controller with a sequential 12 bit a / D converter.  

Ak4181a operates from 2.7V and can operate up to 125 kHz as a sampling frequency.  

It is possible to detect brush pressure in addition to X axis / Y axis position detection. Battery voltage can be measured because it has a reference voltage. In addition, since the temperature sensor is built-in, temperature measurement is also possible. Holds two inputs for external analog voltage measurements.
