LC717A10PJ

Overview

The LC717A10PJ is a high-performance and low-cost capacitance-digital-converter LSI for electrostatic

capacitive touch sensor, especially focused on usability.

It has 16 channels capacitance-sensor input. This makes it ideal for use in the products that need many switches.

Since the calibration function and the judgment of ON/OFF are automatically performed in LSI internal, it can

make development time more short. A detection result (ON/OFF) for each input can be read out by the serial

Also, measurement value of each input can be read out as 8-bit digital data. Moreover, gain and other parameters

can be adjusted using serial interface.

Function

 Detection system: Differential capacitance detection (Mutual capacitance type)

 Input capacitance resolution: Can detect capacitance changes in the femto Farad order

 Measurement interval (16 differential inputs): 30ms (Typ) (at initial configuration),

6ms (Typ) (at minimum interval configuration)

 External components for measurement: Not required

 Current consumption: 570A (Typ) (VDD = 2.8V), 1.3mA (Typ) (VDD = 5.5V)

 Supply voltage: 2.6V to 5.5V

 Detection operations: Switch

 Packages: SSOP30
