CAT5111VI-10-T3

Digital Potentiometers Overview

The CAT5111VI-10-T3 is a single-channel digital potentiometer IC manufactured by onsemi. It features a 10 kOhm resistance value with 100 taps and utilizes non-volatile memory to retain settings without power. The device employs a serial 3-wire interface for control and includes an output buffer. It operates within a supply voltage range of 2.5 V to 6 V, consuming 200 uA of current. Designed for industrial applications, it supports temperatures from -40°C to +85°C and is housed in an SOIC-8 surface-mount package.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper position after power loss
• Serial 3-wire interface for up/down control
• Integrated output buffer for improved drive capability
• Linear taper with 100 discrete tap positions

Digital Potentiometers Applications

• Industrial process control systems requiring adjustable gain or reference voltages
• Consumer electronics needing programmable volume or brightness levels
• Test and measurement equipment utilizing precise resistance calibration

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors as the part status is listed as obsolete. Confirm RoHS compliance details directly with the manufacturer documentation. Check for potential supply chain disruptions due to end-of-life status. Ensure ordering suffixes match specific packaging requirements such as tape and reel quantities.

Digital Potentiometers Selection Notes

Select this model when non-volatile storage is required to maintain resistance settings across power cycles. The 10 kOhm value suits moderate impedance circuits. Verify that the 3-wire serial interface aligns with available microcontroller pins. Consider the SOIC-8 footprint for PCB layout compatibility. Evaluate thermal performance within the specified -40°C to +85°C operating range.

Digital Potentiometers Part Context

This component belongs to the CAT511x series of linear-taper digital potentiometers. Variants differ by resistance value (10k, 50k, 100k), interface type (serial vs. increment/decrement), and package style. The VI suffix indicates industrial temperature range and SOIC-8 packaging, while T3 denotes tape and reel shipping configuration.

Digital Potentiometers Replacement Considerations

Direct substitutes include other CAT5111 variants with different resistance values or packages, such as CAT5111ZI-10-GT3 in MSOP-8. Cross-reference with similar non-volatile digital potentiometers from other manufacturers if pin-out compatibility allows verification.
