CAT5111LI-00

Digital Potentiometers Overview

The CAT5111LI-00 is a single-channel digital potentiometer IC manufactured by onsemi. It features a 100 kOhm resistance value with 100 discrete taps and utilizes non-volatile memory to retain the wiper position upon power loss. The device employs an Increment/Decrement control interface for setting resistance levels. It operates within a supply voltage range of 2.5 V to 6 V, drawing a typical operating current of 200 uA. The component is housed in an MSOP-8 surface-mount package and supports a linear taper profile across an industrial temperature range of -40°C to +85°C.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper settings without external backup power
• 100 kOhm total resistance with 100 adjustable tap positions
• Increment/Decrement serial control interface simplifies microcontroller integration
• Low power consumption with 200 uA typical operating current

Digital Potentiometers Applications

• Automated gain control in instrumentation systems
• Volume or tone adjustment in audio equipment
• Calibration of sensor circuits requiring periodic adjustment
• Voltage reference trimming in measurement devices

Digital Potentiometers Procurement Notes

Verify the specific suffix 'LI' against the manufacturer's latest documentation to confirm the package type (MSOP-8) and extended temperature rating (-40°C to +85°C). Confirm RoHS compliance status directly with onsemi as regulatory requirements may vary by production batch. Check for end-of-life notices or obsolescence warnings before finalizing design-in decisions.

Digital Potentiometers Selection Notes

Select this component when a 100 kOhm resistance value and 100 resolution steps are required for precise analog signal conditioning. Ensure the system architecture supports the Increment/Decrement interface protocol. Compare against the CAT5111VI variant if a 3-wire serial interface or SOIC-8 package is preferred instead of the MSOP-8 form factor.

Digital Potentiometers Part Context

This part belongs to the CAT5111 family of single digital potentiometers designed to replace mechanical trimmers. The 'L' indicates the extended industrial temperature grade, while 'I' denotes the MSOP-8 package. The '00' specifies the 100 kOhm resistance code. This series targets applications needing reliable, software-adjustable resistance without physical access.

Digital Potentiometers Replacement Considerations

Direct pin-compatible alternatives within the same family include the CAT5111VI-00 for different packaging or interface needs. Verify that substitute parts maintain the same non-volatile memory characteristics and Increment/Decrement control logic to ensure circuit compatibility.
