CAT5112VI00

Digital Potentiometers Overview

The CAT5112VI00 is a single digitally programmable potentiometer (DPP) featuring a buffered wiper and non-volatile EEPROM storage. It offers 32 linear tap positions with resistance values of 10kΩ, 50kΩ, or 100kΩ. The device operates on a single supply voltage ranging from 2.5V to 6.0V and utilizes an increment/up-down serial interface controlled by CS, U/D, and INC pins. Packaged in an SOIC-8 format, it retains the wiper setting upon power loss and automatically recalls it during power-up.

Digital Potentiometers Feature Summary

• 32-position linear taper potentiometer with buffered wiper output
• Non-volatile EEPROM memory for wiper position retention
• Single supply operation: 2.5V to 6.0V
• Increment/Up-Down serial control interface

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 resistance value suffix (-10, -50, or -00) required for the application, as the base model number does not specify the terminal resistance. Confirm that the SOIC package variant aligns with the PCB footprint design. Ensure the industrial temperature range rating meets the operational environment requirements.

Digital Potentiometers Selection Notes

Select this component when an electronic replacement for mechanical potentiometers is needed in automated production lines or remote adjustment scenarios. Choose based on the required resistance value (10kΩ, 50kΩ, or 100kΩ). The buffered wiper makes it suitable for voltage divider applications, whereas unbuffered variants are preferred for simple variable resistor uses.

Digital Potentiometers Part Context

The CAT5112 belongs to the DPP family of digitally programmable potentiometers designed to replace mechanical components. It integrates a 32-tap series resistor array with an up/down counter and decoder. The buffered wiper allows it to function effectively as a voltage divider, distinguishing it from other models in the series that may lack buffering.

Digital Potentiometers Replacement Considerations

Direct pin-compatible replacements within the same family include CAT5112LI (PDIP), CAT5112ZI (MSOP), and CAT5112YI (TSSOP) variants, provided the resistance value and temperature grade match. For unbuffered wiper applications, consider the CAT5114 series.
