CAT5241WI50

Digital Potentiometers Overview

The CAT5241WI-50-T1 is a quad digital potentiometer IC from onsemi, featuring four independent linear-taper potentiometers with 64 taps each. It utilizes an I2C serial interface for control and includes 16 bytes of non-volatile memory to store 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 temperature applications from -40°C to +85°C. Packaged in a 20-lead SOIC (W suffix), it offers low wiper resistance and automatic recall of saved settings upon power-up.

Digital Potentiometers Feature Summary

• Four independent digital potentiometers with 64 resistor taps and linear taper
• Integrated I2C serial interface for control and memory access
• Non-volatile memory storage for four wiper settings per potentiometer
• Industrial temperature range operation (-40°C to +85°C)

Digital Potentiometers Applications

• Circuit level adjustments requiring electronic replacement for mechanical potentiometers
• System level calibration and trimming in automated production environments
• Applications requiring periodic adjustment in inaccessible or hazardous locations

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix 'T1' confirms the SOIC-20 package and tape & reel shipping format. Confirm the '-50' designation corresponds to the 50 kOhm resistance value. Check current availability status as distribution channels may list end-of-life notifications for this component series.

Digital Potentiometers Selection Notes

Select the CAT5241WI-50-T1 when four isolated digital potentiometers are required with non-volatile position retention. Ensure the system provides a compatible I2C master controller. Verify that the 50 kOhm resistance value aligns with the target circuit impedance requirements and that the 2.5 V to 6.0 V supply range matches the design voltage.

Digital Potentiometers Part Context

This component belongs to the CAT5241 family of quad digital potentiometers. The 'W' suffix indicates the SOIC-20 package variant, while 'I' denotes the industrial temperature grade. The '50' specifies the 50 kOhm end-to-end resistance. Other variants include TSSOP packages (Y suffix) and different resistance values such as 2.5 kOhm, 10 kOhm, and 100 kOhm.

Digital Potentiometers Replacement Considerations

Direct pin-compatible replacements within the same package and interface include other CAT5241 variants with different resistance values (e.g., CAT5241WI-10-T1). Cross-package alternatives like the CAT5241YI-50-T2 offer identical functionality in a TSSOP-20 footprint but require PCB layout modifications.
