DIGI POT 5 click is a digitally controlled quad potentiometer, with the resistance of 10KΩ. It has an 8bit 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. DIGI POT 5 click 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.DIGI POT 5 click has a multitude of practical uses in electronic circuits. The most popular uses include precision calibration of set point thresholds, sensor trimming, LCD contrast adjustment, audio attenuation, an adjustable gain for amplifiers and offset trimming. DIGI POT 5 click can be used to replace the common mechanical trim pot, in a wide range of different applications where the operating voltage stays within the limits.
