CAT5114ZI-00-T3

Digital Potentiometers Overview

The CAT5114ZI-00-T3 is a single-channel digital potentiometer from onsemi, featuring 32 linear taper positions. It operates within a supply voltage range of 2.5 V to 6.0 V and utilizes an Increment/Up-Down serial interface controlled by CS, U/D, and INC pins. The device incorporates non-volatile EEPROM memory to retain wiper settings during power-down. This specific variant offers a resistance value of 100 kΩ and is housed in an MSOP-8 package.

Digital Potentiometers Feature Summary

• 32-position linear taper potentiometer with non-volatile EEPROM wiper storage
• Increment Up/Down serial interface for simple control
• Single supply operation ranging from 2.5 V to 6.0 V
• Low standby current consumption

Digital Potentiometers Applications

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

Digital Potentiometers Procurement Notes

Verify the ordering suffix 'Z' corresponds to the MSOP-8 package and '-T3' indicates tape and reel shipping. Confirm the 'I' suffix denotes the industrial temperature range (-40°C to +85°C). Ensure the '00' suffix matches the required 100 kΩ resistance value for the specific design application.

Digital Potentiometers Selection Notes

Select this component when a 100 kΩ digital potentiometer with non-volatile memory is required. The MSOP-8 package is suitable for space-constrained designs. The Increment/Up-Down interface simplifies microcontroller integration compared to I2C or SPI variants. Verify that the 32-tap resolution meets the system's adjustment granularity requirements.

Digital Potentiometers Part Context

This part belongs to the CAT5114 family of 32-tap digital potentiometers. The 'ZI' designation specifies the MSOP-8 package and Industrial temperature grade. The '00' indicates the 100 kΩ resistance option. The 'T3' suffix typically denotes tape and reel packaging for automated assembly processes.

Digital Potentiometers Replacement Considerations

Direct replacements include other CAT5114 variants with different resistance values (e.g., CAT5114ZI-10-T3 for 10 kΩ) or packages. Cross-referencing with similar 32-tap digital potentiometers from other manufacturers requires verifying interface compatibility and pinout alignment.
