CAT5116LI-G

Digital Potentiometers Overview

The CAT5116LI-G is a log-taper, single digital potentiometer manufactured by onsemi. It features a 32 kΩ resistance value with 100 tap positions and nonvolatile EEPROM wiper storage. The device operates on a single supply voltage ranging from 2.5 V to 5.5 V and utilizes an Increment/Up-Down serial interface controlled by CS, U/D, and INC pins. Packaged in an 8-pin PDIP, it supports industrial temperatures from -40°C to +85°C.

Digital Potentiometers Feature Summary

• 100-position log-taper potentiometer with 32 kΩ total resistance
• Nonvolatile EEPROM wiper storage retains settings during power loss
• Ultra-low standby current of 10 nA typical
• Increment/Up-Down serial control interface (CS, U/D, INC)

Digital Potentiometers Applications

• Automated product calibration
• Remote control adjustments
• Audio volume control
• Sensor adjustment

Digital Potentiometers Procurement Notes

Verify the 'L' suffix indicates the PDIP-8 package configuration. Confirm RoHS compliance status as the datasheet specifies Pb-Free and Halogen-Free construction for this series. Check for any specific ordering suffix variations that may affect shipping quantities or tape/reel availability versus rail packaging.

Digital Potentiometers Selection Notes

Select the CAT5116LI-G when a log-taper response curve is required rather than linear. Ensure the application voltage stays within the 2.5 V to 5.5 V range. Verify that the 32 kΩ resistance value matches the circuit requirements, noting the ±20% tolerance and 300 ppm/°C temperature coefficient.

Digital Potentiometers Part Context

This component belongs to the CAT5116 family of digitally programmable potentiometers. The 'LI' designation specifically identifies the PDIP-8 through-hole package variant. Other suffixes such as 'VI', 'YI', and 'ZI' correspond to SOIC, TSSOP, and MSOP packages respectively.

Digital Potentiometers Replacement Considerations

Direct pin-compatible replacements include other CAT5116 variants with different packages (e.g., CAT5116VI-G for SOIC). For linear taper requirements, consider the CAT5115 series. Verify that substitute devices support the same 100-tap resolution and nonvolatile memory functionality.
