CAT5114YI-10-GT3

Digital Potentiometers Overview

The CAT5114YI-10-GT3 is a single-channel digital potentiometer IC manufactured by onsemi. It features a 10 kOhm resistance value with 32 taps and utilizes a linear taper profile. The device operates within a supply voltage range of 2.5 V to 6 V, consuming a typical operating current of 100 uA. It employs a nonvolatile memory architecture to retain wiper settings during power loss. Control is managed via a serial 3-wire interface. The component is housed in an 8-pin TSSOP package and supports surface mount installation across an industrial temperature range from -40°C to +85°C.

Digital Potentiometers Feature Summary

• Nonvolatile memory retains wiper position upon power cycle
• Serial 3-wire control interface (CS, U/D, INC)
• Single POT with 32 taps and linear taper
• Low power consumption of 100 uA

Digital Potentiometers Applications

• Automated adjustments on high-volume production lines
• Equipment requiring periodic adjustment in remote or hazardous environments
• Resistive divider configurations for signal conditioning

Digital Potentiometers Procurement Notes

Verify the specific suffix GT3 for tape-and-reel packaging configuration. Confirm the YI designation corresponds to the TSSOP-8 package variant. Check current lifecycle status as distribution data indicates potential end-of-life conditions for this specific part number. Ensure compatibility with 3-wire serial protocols before integration.

Digital Potentiometers Selection Notes

Select this component when nonvolatile storage of the wiper position is required without external EEPROM. Choose the 10 kOhm variant for impedance matching applications. Verify that the 3-wire interface aligns with the host controller's available GPIO pins. Consider the 100 uA current draw for battery-operated systems where low standby power is critical.

Digital Potentiometers Part Context

This part belongs to the CAT5114 series of 32-tap digital potentiometers. It serves as an electronic replacement for mechanical potentiometers. The YI suffix typically denotes the TSSOP-8 package, while GT3 indicates reel packaging. It differs from volatile counterparts like the CAT5110 by retaining settings after power removal.

Digital Potentiometers Replacement Considerations

Direct substitutes include other CAT5114 variants with different resistance values or packages. Cross-reference with CAT5114YI-50-GT3 for 50 kOhm requirements. Verify pinout compatibility if replacing volatile digital potentiometers.
