CAT5241WI-10-T1

Digital Potentiometers Overview

The CAT5241WI-10-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 non-volatile memory (NVRAM) for wiper position storage. The device operates within a supply voltage range of 2.5 V to 6.0 V and supports industrial temperature ranges (-40°C to +85°C). Each potentiometer offers an end-to-end resistance of 10 kΩ with ±20% tolerance. The component utilizes a 20-lead SOIC package and includes features such as automatic recall of saved settings at power-up and low standby current.

Digital Potentiometers Procurement Notes

Verify the specific suffix 'T1' corresponds to the SOIC-20 package and tape & reel shipping format as defined in the ordering information table. Confirm that the 'I' suffix indicates the industrial temperature grade. Check current availability status as distribution channels may vary.

Digital Potentiometers Selection Notes

Select this part when four isolated digital potentiometers are required on a single chip. Ensure the system voltage falls between 2.5 V and 6.0 V. Verify that the 10 kΩ resistance value matches the circuit requirements. Consider the 20-lead SOIC footprint for PCB layout compatibility.

Digital Potentiometers Part Context

This component belongs to the CAT5241 family of quad digital potentiometers. Variants exist with different resistance values (2.5 kΩ, 50 kΩ, 100 kΩ) and package types (TSSOP-20). The WI-10 designation specifically identifies the 10 kΩ version in the SOIC-20 package.

Digital Potentiometers Replacement Considerations

Direct substitutes include other CAT5241 variants with different resistance values or packages, such as CAT5241YI-10-T2 (TSSOP-20). Cross-family replacements require verification of pinout compatibility and electrical specifications.
