LC717A10AJ
CMOS LSI
Capacitance-Digital-Converter LSI
for Electrostatic Capacitive Touch
Sensors

Overview
The LC717A10AJ 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 interface (I2C
compatible bus or SPI).
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.
Features
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
Interface: I2C * compatible bus or SPI selectable.
Current consumption: 570μA (Typ) (VDD = 2.8V), 1.3mA (Typ) (VDD = 5.5V)
Supply voltage: 2.6V to 5.5V
Detection operations: Switch
Packages: SSOP30
