CAT5114VI-00-G

Digital Potentiometers Overview

The CAT5114VI-00-G is an onsemi single digital potentiometer in an SOIC-8 package with a 100 kΩ resistance value. It features a 32-tap linear taper resistor array controlled via a serial interface using CS, U/D, and INC pins. The device operates on a single supply voltage ranging from 2.5 V to 6.0 V. Key electrical characteristics include a wiper current of ±4.4 mA, integral linearity error of 0.5 LSB typical, and differential linearity error of 0.25 LSB typical. Nonvolatile EEPROM storage retains the wiper position during power-down, ensuring automatic reinstatement upon power restoration.

Digital Potentiometers Feature Summary

• 32-position linear taper potentiometer with nonvolatile EEPROM wiper storage
• Single supply operation from 2.5 V to 6.0 V with low standby current
• Increment Up/Down serial interface for wiper control
• Industrial temperature range (-40°C to +85°C) and RoHS compliant

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 specific ordering suffix 'V' corresponds to the SOIC-8 package and '-00' indicates the 100 kΩ resistance value as per the manufacturer's ordering guide. Confirm that the 'G' suffix denotes lead-free, halogen-free, and RoHS compliance. Ensure the industrial temperature grade ('I') meets the operational environmental requirements of the target application before procurement.

Digital Potentiometers Selection Notes

Select this component when a digitally adjustable 100 kΩ resistive element is required with persistent memory settings. The 32-tap resolution provides approximately 3.2% step accuracy. Consider the SOIC-8 package dimensions if board space allows for standard surface-mount assembly. Verify that the system logic levels are compatible with the CMOS input thresholds defined for the operating voltage range of 2.5 V to 6.0 V.

Digital Potentiometers Part Context

The CAT5114 series serves as an electronic replacement for mechanical potentiometers, enabling automated adjustments in high-volume production lines. This specific variant utilizes the SOIC-8 footprint, offering a compact solution compared to through-hole packages like PDIP. The device integrates a seven-bit up/down counter and decoder to manage the 32 available tap positions within the resistor array.

Digital Potentiometers Replacement Considerations

Direct pin-compatible substitutes within the same family include CAT5114LI-00-G (PDIP), CAT5114YI-00-G (TSSOP), and CAT5114ZI-00-G (MSOP). Cross-model comparisons should verify identical resistance values and package footprints. Other digital potentiometers may require interface adaptation or level shifting if their control protocols differ from the three-wire serial interface used here.
