CAT5221YI25

Digital Potentiometers Overview

The CAT5221YI-25-T2 is a digital potentiometer IC from onsemi featuring two independent wipers with non-volatile memory. It utilizes an I2C serial interface for control and offers 64 tap positions per potentiometer. The device operates within a supply voltage range of 2.5 V to 6 V, with typical operation at 3.3 V or 5 V. The total resistance is 2.5 kOhms with a linear taper. It is housed in a TSSOP-20 surface-mount package and draws approximately 1 mA of operating current.

Digital Potentiometers Feature Summary

Dual-channel digital potentiometer configuration
Non-volatile brush memory retains settings without power
I2C serial interface for simplified connectivity
Linear taper with 64 discrete tap positions

Digital Potentiometers Part Context

This component belongs to the CAT5221 series of digital potentiometers. It is distinct from other variants such as the CAT5221WI-25-T1, which uses a SOIC-20 package instead of TSSOP-20. Both share similar electrical characteristics but differ in physical footprint and specific manufacturer packaging details.

Digital Potentiometers Replacement Considerations

Verify pin compatibility when substituting with the CAT5221WI-25-T1, noting the package difference between TSSOP-20 and SOIC-20. Ensure the replacement supports the required I2C address configuration and non-volatile memory retention features.
