LC717A30UR Datasheet - ON Semiconductor

LC717A30UR Capacitance-Digital-Converter LSI

Power supply (+2.6 V to +5.5 V) (Note 1) Ground (Notes 1, 2) 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 ca.

LC717A30UR Capacitance‐Digital‐Converter LSI for Electrostatic Capacitive Touch Sensors The LC717A30UR is a high performance, low cost, and highly usable capacitance converter for electrostatic capacitive touch and proximity sensors. 8 capacitance-sensing input channels ideal for use in any end products that needs an array of switches. The LC717A30UR facilitates a short system development time through its automatic calibration function and minimal external components. The detection result (ON/.
