CAT522WI

Digital Potentiometers Overview

The CAT522WI is a single digitally programmable potentiometer from onsemi, housed in a 14-SOIC package. It features a linear taper with an end-to-end resistance of 24 kΩ and 63 resistive elements providing 64 taps. The device operates within a supply voltage range of 2.5 V to 5.5 V and utilizes a serial interface for control. It includes non-volatile memory to retain wiper settings during power loss.

Digital Potentiometers Feature Summary

• Integrates a single digitally programmable potentiometer with non-volatile memory storage
• Enables precise resistance adjustment via serial communication interface
• Maintains programmed wiper position automatically upon power restoration

Digital Potentiometers Applications

• Programmable voltage reference circuits
• Gain control in signal conditioning systems
• Calibration of analog measurement equipment

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors or certified secondary market suppliers. Confirm the specific suffix matches the required package and temperature grade. Request original manufacturer documentation to validate part history and ensure compliance with current specifications before integration into production designs.

Digital Potentiometers Selection Notes

Select this component when a single-channel digital potentiometer with 24 kΩ resistance is required. Ensure the system design supports the necessary serial interface protocol. Verify that the operating voltage range aligns with the available power supply rails and that the industrial temperature rating meets environmental requirements.

Digital Potentiometers Part Context

This component belongs to the CAT522 series of digitally programmable potentiometers. It shares architectural similarities with other parts in the family but differs in channel count and specific resistance values. The series provides solutions for replacing mechanical potentiometers in applications requiring digital control and data retention capabilities.

Digital Potentiometers Replacement Considerations

Direct replacements include the CAT5221WI-10-T1 for dual-channel configurations. Cross-reference pinouts and electrical characteristics carefully. Verify that alternative parts support the same serial interface and non-volatile memory functions.
