DIGI POT 5 Click Board

Overview

The DIGI POT 5 Click Board™ is a digitally controlled quad potentiometer, with a resistance of 10Kohm. It has an 8-bit wiper step resolution, which allows the wiper to take 257 different discrete positions (across 256 internal resistors). The digital wiper position can be controlled via the SPI interface.

The DIGI POT 5 Click Board™ features a durable EEPROM non-volatile (NV) memory for storing the wiper position. The content of the wiper register memory located in the NV memory is copied to the actual wiper registers after the power-on or reset state, so the device acts similar to its mechanical counterpart, recalling its last used wiper position after being powered on. The device also features the WiperLock technology, which effectively locks the wiper position in place.
