The LC717A30UJ 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 LC717A30J facilitates a short system development time through its automatic calibration function and minimal external components. The detection result (ON/OFF) for each sensor is read out by the serial interface (I
C or SPI).
