CAT5241WI25

Digital Potentiometers Overview

The CAT5241WI-25 is a quad digitally programmable potentiometer (DPP) manufactured by onsemi. It features four independent 64-tap wipers with non-volatile memory to retain settings during power loss. The device utilizes an I2C serial control interface for communication. Nominal resistance is 25 kΩ with a tolerance of ±20% and a temperature coefficient of 300 ppm/°C. It operates on a single supply voltage ranging from 2.5 V to 6 V, drawing approximately 1 mA of current. The component is housed in a 20-pin SOIC package and supports an operating temperature range from -40°C to +85°C.

Digital Potentiometers Feature Summary

• Quad configuration with four independent 64-position wipers
• Non-volatile NVRAM retains wiper settings without power
• I2C serial control interface for digital adjustment
• Linear taper resistance characteristic

Digital Potentiometers Applications

• Automated product calibration systems
• Remote control adjustment of equipment
• Offset, gain, and zero adjustments in adaptive control systems

Digital Potentiometers Procurement Notes

Verify the specific suffix 'T1' or 'TE13' required for tape-and-reel packaging when ordering. Confirm availability status as this series may be subject to discontinuation notices. Ensure the I2C address configuration matches the system design requirements before integration.

Digital Potentiometers Selection Notes

Select this model for applications requiring four independent variable resistors controlled via I2C. The 25 kΩ value suits moderate impedance circuits. Verify that the 64-tap resolution meets the precision requirements, as higher tap counts are available in other variants within the family.

Digital Potentiometers Part Context

This component belongs to the CAT5241 family of linear-taper digital potentiometers. It shares architectural similarities with the CAT5221 but offers four channels instead of two. The part integrates buffered wiper outputs and common reference inputs suitable for DAC-like applications.

Digital Potentiometers Replacement Considerations

Direct replacements include CAT5241YI-25-T1 for TSSOP packaging or CAT5241WI-25-T1 for identical SOIC form factor. Cross-model substitutes like CAT5242 offer similar functionality with different interface options.
