CAT5112VI-00

Digital Potentiometers Overview

The CAT5112VI-00 is a single-channel digital potentiometer IC manufactured by onsemi. It features a 10 kOhms resistance value with 32 taps and utilizes an Increment-Decrement control interface. The device incorporates non-volatile memory to retain the wiper position during power-off events. It operates within a supply voltage range of 2.5 V to 6 V, with typical operation at 3.3 V or 5 V, and consumes approximately 200 uA of current. The component is housed in an SOIC-8 surface-mount package and supports commercial temperature ranges.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper settings across power cycles
• Increment-Decrement (Up/Down) digital control interface
• Buffered wiper output for improved drive capability
• Linear taper resistance characteristic

Digital Potentiometers Applications

• Automated gain control in instrumentation systems
• Volume and tone adjustment in audio equipment
• Calibration of sensor circuits requiring periodic adjustment
• Voltage reference trimming in data acquisition systems

Digital Potentiometers Procurement Notes

Verify the specific suffix code against official onsemi documentation to confirm pinout compatibility and electrical tolerances. Confirm that the Increment-Decrement interface matches the system controller's GPIO configuration. Check for end-of-life status as variants in this family may have different availability statuses.

Digital Potentiometers Selection Notes

Select this model when a simple two-wire serial-like control (Up/Down) is preferred over SPI/I2C interfaces. Ensure the 10 kOhms resistance value aligns with the target circuit impedance requirements. Verify that the SOIC-8 package footprint fits the PCB layout constraints compared to DIP alternatives.

Digital Potentiometers Part Context

This component belongs to the CAT5112 family of 32-tap digital potentiometers. It serves as an electronic replacement for mechanical potentiometers in applications where manual adjustment is impractical. The series offers various resistance values and packaging options to suit different industrial and consumer electronics needs.

Digital Potentiometers Replacement Considerations

CAT5112VI-10-G: Verified alternative with identical electrical specifications and interface, differing primarily in RoHS compliance marking and potential minor manufacturing lot variations.

Digital Potentiometers FAQ

What type of memory does the CAT5112VI-00 use?

It uses non-volatile memory to store the wiper position, ensuring the setting is retained after power loss.

How is the wiper position controlled?

The wiper is adjusted using an Increment-Decrement interface, which requires two control pins to move the wiper up or down through the 32 taps.

Is the wiper buffered?

Yes, the CAT5112VI-00 includes a buffered wiper output, allowing it to drive loads more effectively than unbuffered digital potentiometers.
