CAT5115ZI-00T-MP

Digital Potentiometers Overview

The CAT5115ZI-00T-MP is a single-channel digital potentiometer manufactured by onsemi. It features a 32-tap resistive array controlled via an increment/decrement interface. The device operates within a temperature range of -40°C to +85°C and is housed in an 8-pin SOIC package. This component serves as an electronic replacement for mechanical potentiometers, utilizing nonvolatile memory to retain the wiper position upon power loss.

Digital Potentiometers Feature Summary

• 32-tap series resistor array with up/down counter control
• Nonvolatile memory retains wiper setting during power-off
• Increment/Decrement control interface requiring three input pins

Digital Potentiometers Applications

• Automated adjustments on high-volume production lines
• Remote or hazardous environment equipment adjustment
• Electronic replacement for mechanical potentiometers

Digital Potentiometers Procurement Notes

Verify the specific suffix 'MP' against official onsemi documentation, as standard listings typically use suffixes like 'ZI-00-GT3'. Confirm current availability status, as related variants such as CAT5115ZI-00-GT3 have been marked as End-of-Life (EOL) in distributor records. Ensure the ordering part number matches the exact package and resistance tolerance requirements.

Digital Potentiometers Selection Notes

Select this component when a compact, nonvolatile digital solution is required to replace mechanical pots. The 32-tap resolution may be insufficient for applications demanding higher precision; consider the CAT5116 which offers 100 taps if finer adjustment steps are necessary. Verify that the 8-pin SOIC footprint fits the PCB layout constraints.

Digital Potentiometers Part Context

This part belongs to the CAT5115 family of digital potentiometers from onsemi (formerly Catalyst Semiconductor). The family includes variants with different resistance values and tap counts, such as the CAT5116. The 'ZI' designation typically indicates the SOIC-8 package type.

Digital Potentiometers Replacement Considerations

Direct substitutes include other parts within the CAT5115 family, such as CAT5115VI-10-G. For applications requiring higher resolution, the CAT5116 (100 taps) is a compatible alternative within the same product line.
