Renesas Electronics Corporation Digital Potentiometers X9C102SIT2

The X9C102SIT2 is a digitally controlled potentiometer featuring a 1kOc resistance and a three-wire interface for wiper position control. It consists of a resistor array with 99 elements and 100 wiper tap points, allowing it to function as either a three-terminal potentiometer or a two-terminal variable resistor. The device supports non-volatile memory, enabling the storage and recall of the wiper position upon power-up. It operates with a supply voltage of 5V, with a maximum active current of 3mA and a standby current of 750µA. The X9C102SIT2 is available in both 8-lead SOIC and PDIP packages, and it is RoHS compliant. Its high reliability is demonstrated by an endurance rating of 100,000 data changes per bit and a data retention period of up to 100 years. This product is suitable for various applications, including control, signal processing, and parameter adjustment.
