CAT5112LI-00-G

Digital Potentiometers Overview

The CAT5112LI-00-G is a single-channel digital potentiometer IC manufactured by onsemi. It features a non-volatile memory architecture with 32 taps and a linear taper, housed in an 8-pin PDIP package. The device operates within a supply voltage range of 2.5 V to 6 V, with typical operation at 3.3 V or 5 V, and draws a maximum operating current of 200 uA. It utilizes a serial 3-wire interface for control and maintains functionality across an industrial temperature range from -40°C to +85°C.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper position upon power loss
• 32-tap series resistor array with linear taper
• Serial 3-wire up/down control interface
• Buffered wiper output

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

This component is listed as obsolete (End-of-Life) by the manufacturer. Availability is restricted, and distributors may not stock this item in all regions. Verification of current lifecycle status and sourcing channels is required before procurement planning.

Digital Potentiometers Selection Notes

Select this part for applications requiring a single digital potentiometer with non-volatile storage and a 100 kOhm resistance value. Ensure the design supports a 3-wire serial interface and operates within the 2.5 V to 6 V supply range. The PDIP-8 package is suitable for through-hole mounting.

Digital Potentiometers Part Context

The CAT5112LI-00-G belongs to the CAT5112 family of 32-tap digital potentiometers. The suffix 'LI' indicates a 100 kOhm resistance value and a PDIP-8 package, while '00' specifies the non-volatile memory type. This distinguishes it from other variants like the CAT5112VI-10-G, which offers a 10 kOhm value in an SOIC-8 package.

Digital Potentiometers Replacement Considerations

Direct substitutes include other CAT5112 variants with matching electrical characteristics but different packages or resistance values, such as CAT5112ZI-50-G (50 kOhm, MSOP-8). Cross-referencing datasheets for pin compatibility and interface protocols is necessary when considering alternative components.
