LC717A00AR Datasheet (ON Semiconductor) - Capacitance-Digital-Converter LSI

LC717A00AR, Capacitance-Digital-Converter LSI

LC717A00AR Capacitance‐Digital‐Converter LSI for Electrostatic Capacitive Touch Sensors Overview The LC717A00AR is a high-performance, low-cost capacitance- digital-converter LSI for electrostatic capacitive touch sensor, especially focused on usability.

It has 8 channels capacitance-sensor input.

The built-in logic circuit can detect the state (ON/OFF) of each input and output the result.

This makes it ideal for various switch applications.

The calibration function is automatically performed
