LC717A30UJ - ON Semiconductor

LC717A30UJ Capacitance-Digital-Converter LSI

Power supply (+2.6 V to +5.5 V) (Note 1) Ground (Notes 1, 2) Connect to Ground Sensor inputs. Cin0 to Cin7 are connected to the inverting input of the 1st amplifier through the multiplexer. All unused input pins must remain open. Cdrv and Cin printed circuit board patterns should be close to each other as they are capacitively coupled. Test pin, must remain .
