CAT5113VI-01-GT3

Digital Potentiometers Overview

The CAT5113VI-01-GT3 is a single-channel digital potentiometer IC from onsemi, featuring 100 linear taps and non-volatile EEPROM storage. It operates on a single supply voltage ranging from 2.5 V to 6.0 V with an ultra-low standby current of 10 nA. The device utilizes a three-wire serial interface (CS, U/D, INC) for up/down control. Key electrical parameters include a resistance tolerance of ±20%, a temperature coefficient of 300 ppm/°C, and a maximum wiper current of 4.4 mA. It is housed in an SOIC-8 package.

Digital Potentiometers Feature Summary

• 100-position linear taper potentiometer with non-volatile EEPROM wiper storage
• Single supply operation: 2.5 V to 6.0 V
• Ultra-low standby current: 10 nA
• Increment Up/Down serial interface (3-Wire)

Digital Potentiometers Applications

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

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix 'GT3' corresponds to the SOIC-8 tape and reel packaging configuration as defined in the manufacturer's documentation. Confirm that the 'V' suffix indicates the SOIC package type and 'I' denotes the industrial temperature range (-40°C to +85°C). Ensure compliance with RoHS and lead-free requirements specified for this part number.

Digital Potentiometers Selection Notes

Select this component when a 1 kΩ resistance value with 100 discrete steps is required. The non-volatile memory feature ensures the wiper position is retained after power loss. Verify that the system interface supports the three-pin serial control scheme (CS, U/D, INC) and that the operating voltage falls within the 2.5 V to 6.0 V range.

Digital Potentiometers Part Context

This part belongs to the CAT5113 family of 100-tap digital potentiometers. The 'VI' designation specifies the Industrial temperature grade and SOIC-8 package. The '01' indicates the 1 kΩ resistance value. The 'GT3' suffix typically denotes the tape and reel shipping format for high-volume manufacturing.

Digital Potentiometers Replacement Considerations

Direct pin-compatible replacements within the same family include CAT5113VI-10-GT3 (10 kΩ), CAT5113VI-50-GT3 (50 kΩ), and CAT5113VI-00-GT3 (100 kΩ). Other packages such as TSSOP-8 (Y suffix) or MSOP-8 (Z suffix) are available but require layout changes.
