CAT5241WI-00-T1

Digital Potentiometers Overview

The CAT5241WI-00-T1 is a quad digital potentiometer IC from onsemi, featuring four independent linear-taper potentiometers with 64 taps each. It integrates I2C serial interface logic and 16 bytes of non-volatile RAM (NVRAM) for storing up to four wiper settings per channel. The device operates within a supply voltage range of 2.5 V to 6.0 V and supports industrial temperatures from -40°C to +85°C. Each potentiometer has an end-to-end resistance of 100 kΩ, with a typical wiper resistance of 80 Ω at 5 V. The unit is housed in a 20-lead SOIC package.

Digital Potentiometers Feature Summary

• Four independent 64-tap linear digital potentiometers with 100 kΩ resistance
• I2C serial interface for control and memory access
• Non-volatile memory stores four wiper settings per potentiometer with automatic recall on power-up
• Industrial temperature range (-40°C to +85°C) and 2.5 V to 6.0 V operation

Digital Potentiometers Applications

• Circuit level adjustments in electronic systems
• System level calibration and configuration
• Variable resistor applications requiring digital control

Digital Potentiometers Procurement Notes

Verify the specific suffix 'W' indicates the SOIC-20 package and '00' denotes 100 kΩ resistance. Confirm the 'T1' suffix corresponds to tape and reel shipping quantities as specified in the ordering information table. Ensure compatibility with I2C bus protocols and address pin configurations before integration.

Digital Potentiometers Selection Notes

Select this component when four isolated digital potentiometers are required in a single package. The 100 kΩ value suits high-impedance signal paths. Verify that the system can accommodate the 20-pin SOIC footprint and that the I2C address pins (A0-A3) can be configured to avoid bus conflicts with other devices.

Digital Potentiometers Part Context

This part belongs to the CAT5241 family of quad digital potentiometers. Variants differ by resistance value (2.5k, 10k, 50k, 100k) and package type (SOIC or TSSOP). The WI-00-T1 specifically designates the 100 kΩ version in the SOIC-20 package shipped in reels.

Digital Potentiometers Replacement Considerations

Direct replacements include other CAT5241 variants with different resistance values or packages, such as CAT5241YI-00-T2 (TSSOP-20). Cross-family replacements require verifying pinout compatibility and I2C register mapping.
