CAT51x Linear-Taper Digital Potentiometers onsemi CAT51x Linear-Taper Digital Potentiometers allow one-time calibration through integrated EEPROM memory and control logic. These potentiometers retain the setting even if the power is lost. The CAT51x Digital Potentiometers offer 128 taps and an increment-decrement interface. These potentiometers include fast up/down wiper control mode, non-volatile wiper setting storage, and automatic wiper setting recall at power-up. The onsemi CAT51x Digital Potentiometers are ideal for calibration and control functions in high-voltage (15V) consumer, industrial, and medical applications.
