Capacitance Digital Converter LSI 30-Pin SSOP T/R

Capacitance Digital Converter LSI 30-Pin SSOP T/R

Manufacturer Part #: LC717A00AJ-AH

Alternate Part #: LC717A00AJ-AH/BKN

The LC717A00AJ 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.
