CAT5241WI-50-T1

Digital Potentiometers Overview

The CAT5241WI-50-T1 is a quad digital potentiometer IC featuring four independent linear-taper potentiometers, each with 64 taps. It integrates I2C serial interface logic and non-volatile memory (NVRAM) to store up to four wiper settings per channel. The device operates on a 2.5 V to 6.0 V supply with a typical standby current of less than 1 µA. Key electrical parameters include a 50 kΩ end-to-end resistance with ±20% tolerance, a maximum wiper resistance of 150 Ω at 5 V, and an operating temperature range of -40°C to +85°C. It supports 1,000,000 write cycles and 100-year data retention.

Digital Potentiometers Feature Summary

• Four independent 64-tap linear digital potentiometers with I2C control
• Non-volatile memory stores four distinct wiper positions per potentiometer
• Automatic recall of DR0 settings upon power-up
• Industrial temperature range (-40°C to +85°C) in SOIC-20 package

Digital Potentiometers Applications

• Circuit level adjustments for gain or offset calibration
• System level volume or tone control in audio equipment
• Automated trimming in high-volume production lines
• Remote or hazardous environment equipment requiring periodic adjustment

Digital Potentiometers Procurement Notes

Verify the specific suffix 'T1' corresponds to the SOIC-20 tape and reel packaging configuration as defined in the ordering information. Confirm that the 'I' suffix indicates the industrial temperature grade. Ensure the host system voltage aligns with the 2.5 V to 6.0 V operational limits before integration.

Digital Potentiometers Selection Notes

Select this component when four isolated digital potentiometers are required on a single bus. The 50 kΩ resistance value suits moderate impedance applications. Consider the TSSOP-20 variant if a smaller footprint is necessary, noting the different shipping quantity. Verify address pin configurations (A0-A3) allow for unique addressing if multiple devices share the I2C bus.

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-20 or TSSOP-20). The 'WI' designation specifically identifies the SOIC-20 package with industrial temperature rating, while 'YI' denotes the TSSOP-20 package.

Digital Potentiometers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should evaluate other CAT5241 variants with different resistance values or packages if physical compatibility allows.
