The CAT5259WI-50-T1 is a quad digital potentiometer featuring four linear taper potentiometers with 256 taps each. It operates with an end-to-end resistance of 50 kOc and utilizes an I¬=C interface for control and memory access. Each potentiometer includes non-volatile memory capable of storing up to four wiper settings, which are automatically recalled upon power-up. The device supports a wide operating voltage range of 2.5 to 6.0 V and has a low standby current of less than 1 ¬µA. It is available in both SOIC and TSSOP packages, suitable for commercial and industrial temperature ranges from -40¬8C to 85¬8C. The CAT5259WI-50-T1 is designed for applications requiring precise circuit-level adjustments and offers a high endurance of 1,000,000 write cycles with a data retention period of up to 100 years.
