HOW DOES IT WORK?
DIGI POT 14 Click is based on the TPL0102, a dual-channel digital potentiometer with non-volatile memory from Texas Instruments. It is a two-channel linear-taper digital potentiometer. Each potentiometer can be used as a three-terminal potentiometer or a two-terminal rheostat. When the TPL0102 is powered down, it saves the last values of wipers in EEPROM, and when the power is restored, the positions of wipers are loaded to their initial position. The TPL0102 features a fast power-up response time to wiper settings under 100μs, single-supply, and dual-supply operation ranges.
DIGI POT 14 Click uses a standard 2-Wire I2C interface to communicate with the host MCU and supports Standard and Fast mode with up to 400kHz of clock frequency. The I2C address can be set over the ADDR SEL jumpers, where 0 is set by default. Both potentiometers' high, low, and wiper pins are tied to screw terminals, properly labeled as A and B sides.
This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. Also, this Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used as a reference for further development.
