CAT5113YI-50-GT3

Digital Potentiometers Overview

The CAT5113YI-50-GT3 is a single digital potentiometer IC from onsemi, featuring a 50 kΩ resistance value with linear taper and 100 tap positions. It utilizes an Increment/Up-Down serial interface for wiper control and includes nonvolatile EEPROM memory to retain settings during power loss. The device operates on a single supply voltage ranging from 2.5 V to 6.0 V, drawing ultra-low standby current of 10 nA. Packaged in a TSSOP-8 (Y suffix) format with NiPdAu lead finish, it is designed as an electronic replacement for mechanical potentiometers in automated calibration and remote adjustment applications.

Digital Potentiometers Feature Summary

• 100-position linear taper potentiometer with 50 kΩ nominal resistance
• Non-volatile EEPROM wiper storage retains position after power down
• Increment/Up-Down serial interface using CS, U/D, and INC pins
• Single supply operation from 2.5 V to 6.0 V with 10 nA standby current

Digital Potentiometers Applications

• Automated product calibration
• Remote control adjustments
• Offset, gain, and zero control circuits
• Tamper-proof calibrations
• Programmable analog functions

Digital Potentiometers Procurement Notes

Verify the 'Y' suffix confirms the TSSOP-8 package and 'GT3' indicates tape and reel shipping. Confirm the 'I' suffix denotes the industrial temperature range (-40°C to +85°C). Ensure the '-50' designation matches the required 50 kΩ resistance value for the specific circuit design.

Digital Potentiometers Selection Notes

Select this component when a 50 kΩ digital potentiometer with nonvolatile memory is required. The TSSOP-8 package suits space-constrained PCB layouts. Verify that the system logic levels are compatible with the CMOS input requirements and that the 100-tap resolution meets the application's precision needs.

Digital Potentiometers Part Context

This part belongs to the CAT5113 family of 100-tap digital potentiometers. The 'Y' suffix specifically identifies the TSSOP-8 package variant, while other suffixes like 'V', 'Z', and 'L' correspond to SOIC-8, MSOP-8, and PDIP-8 packages respectively. All variants share the same core functionality and electrical characteristics.

Digital Potentiometers Replacement Considerations

Direct pin-compatible replacements within the same family include CAT5113VI-50-GT3 (SOIC-8) or CAT5113ZI-50-T3 (MSOP-8), provided the package footprint allows. For different resistance values, check CAT5113YI-10-GT3 (10 kΩ) or CAT5113YI-00-GT3 (100 kΩ).
