LC717A00AJ

Overview

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.

The calibration function is automatically performed by the built-in logic circuit during power activation or whenever

there are environmental changes. In addition, since initial settings of parameters, such as gain, are configured,

LC717A00AJ can operate as stand-alone when the recommended switch pattern is applied.

external devices whenever necessary. Moreover, outputs of the 8-input capacitance data can be detected and measured

as 8-bit data.
