CAT5113YI-01-GT3

Digital Potentiometers Overview

The CAT5113YI-01-GT3 is a single-channel digital potentiometer featuring a 1 kΩ resistance value with linear taper and 100 tap positions. It operates on a single supply voltage ranging from 2.5 V to 6.0 V, drawing a maximum standby current of 1 µA. The device utilizes a nonvolatile EEPROM to retain the wiper position during power loss, automatically restoring it upon power-up. Control is managed via a three-wire serial interface consisting of Chip Select (CS), Up/Down (U/D), and Increment (INC) pins. The component is housed in an 8-pin TSSOP package.

Digital Potentiometers Feature Summary

• 100-position linear taper potentiometer with 1 kΩ nominal resistance
• Nonvolatile EEPROM storage retains wiper setting across power cycles
• Ultra-low standby current consumption of 10 nA typical
• Increment/Up-Down serial control interface requiring only three pins

Digital Potentiometers Applications

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

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix 'YI' corresponds to the TSSOP-8 package and NiPdAu lead finish as defined in the manufacturer's documentation. Confirm that the '-GT3' designation indicates tape and reel shipping quantities. Ensure compliance with RoHS and halogen-free requirements for the target application environment.

Digital Potentiometers Selection Notes

Select this part when a 1 kΩ resistance range is required alongside nonvolatile memory retention. The industrial temperature range (-40°C to +85°C) supports operation in varied environmental conditions. Verify that the 100-tap resolution meets the system's adjustment precision needs compared to lower-resolution alternatives.

Digital Potentiometers Part Context

This component belongs to the CAT5113 family of 100-tap digital potentiometers. The 'Y' suffix identifies the TSSOP-8 package variant, while 'I' denotes the industrial temperature rating. The '01' indicates the 1 kΩ resistance option, distinguishing it from 10 kΩ, 50 kΩ, or 100 kΩ variants within the same series.

Digital Potentiometers Replacement Considerations

Direct substitutes include other CAT5113 variants with different resistance values or packages, such as CAT5113VI-01-GT3 (SOIC-8) or CAT5113ZI-01-T3 (MSOP-8). Cross-family replacements require verification of pin compatibility and interface protocols.
