CAT5112LI-10-G

Digital Potentiometers Overview

The CAT5112LI-10-G is a single-channel digital potentiometer manufactured by onsemi. It features a 10 kΩ resistance value with 32 taps and linear taper characteristics. The device utilizes non-volatile memory to retain wiper settings upon power loss. Control is managed via a serial 3-wire interface, supporting operation within a supply voltage range of 2.5 V to 6 V. Designed for through-hole mounting in an 8-pin PDIP package, it operates reliably across temperatures from -40°C to +85°C.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper position after power cycles
• Serial 3-wire control interface for up/down adjustment
• Buffered wiper output capability
• Linear resistance taper with 32 tap positions

Digital Potentiometers Applications

• Automated adjustments on high-volume production lines
• Equipment requiring periodic adjustment in hazardous or remote environments
• Electronic replacement for mechanical potentiometers

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized onsemi distributors. Confirm the specific suffix 'LI-10-G' matches required resistance and packaging specifications. Check current lifecycle status as discontinuation notices may affect long-term availability.

Digital Potentiometers Selection Notes

Select this model for applications requiring non-volatile storage and buffered outputs. Ensure the 10 kΩ resistance and 32-tap resolution meet circuit requirements. Verify that the PDIP-8 through-hole package fits the PCB layout constraints compared to surface-mount alternatives.

Digital Potentiometers Part Context

This component belongs to the CAT5112 family of digital potentiometers. Variants within the series differ primarily in resistance values (e.g., 10 kΩ vs 100 kΩ) and package types (PDIP vs MSOP/SOIC). The 'LI' designation typically indicates the specific resistance and temperature grade configuration.

Digital Potentiometers Replacement Considerations

Direct substitutes include other CAT5112 variants with matching 10 kΩ resistance and non-volatile features. Surface-mount equivalents like CAT5112ZI-10-G offer identical electrical performance in MSOP-8 packages. Verify pin compatibility before substitution.
