CAT5114VI-10-G

Digital Potentiometers Overview

The CAT5114VI-10-G is a single-channel digital potentiometer IC from the CAT5114 series, manufactured by onsemi. It features 32 linear taper taps and utilizes non-volatile EEPROM for wiper position storage, retaining settings after power loss. The device operates on a single supply voltage ranging from 2.5 V to 6.0 V with a typical standby current of 100 µA. It employs an increment/decrement serial interface for control. The component is housed in an SOIC-8 surface-mount package and is rated for operation within a temperature range of -40°C to +85°C.

Digital Potentiometers Feature Summary

• Non-volatile EEPROM wiper storage retains resistance settings without power
• 32-position linear taper potentiometer with 10 kΩ nominal resistance
• Low standby current consumption of 100 µA
• Increment/Down serial control interface for easy integration

Digital Potentiometers Applications

• Automated product calibration in high-volume manufacturing
• Remote control adjustments for inaccessible or hazardous equipment
• Offset, gain, and zero control in signal conditioning circuits
• Tamper-proof calibration systems requiring persistent settings

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized onsemi distributors or certified suppliers. Confirm RoHS compliance status and check for end-of-life notices, as availability may vary. Ensure the SOIC-8 package matches the target PCB footprint and that the voltage requirements align with the system design before procurement.

Digital Potentiometers Selection Notes

Select this model when non-volatile memory is required to maintain wiper positions across power cycles. Compare against volatile variants like the CAT5115 if power retention is unnecessary. Verify that the 10 kΩ resistance value fits the circuit impedance requirements and that the SOIC-8 package is compatible with the assembly process.

Digital Potentiometers Part Context

This component belongs to the CAT5114 family of 32-tap digitally programmable potentiometers. It serves as an electronic replacement for mechanical potentiometers, offering improved reliability and automation capabilities. The 'VI' suffix typically denotes the SOIC-8 package variant within this series.

Digital Potentiometers Replacement Considerations

Direct substitutes include other CAT5114 variants with different packages (e.g., TSSOP, PDIP) or resistance values (50 kΩ, 100 kΩ). Cross-reference with CAT5115 series components only if non-volatile storage is not required.
