CAT5112ZI-50

Digital Potentiometers Overview

The CAT5112ZI-50-G is a single-channel digital potentiometer manufactured by onsemi. It features a 50 kΩ resistance value with 32 discrete tap positions and linear taper characteristics. The device utilizes an increment/decrement control interface for wiper adjustment and includes nonvolatile memory to retain settings during power loss. It operates within a supply voltage range of 2.5 V to 6 V, consuming 200 µA of current. The component is housed in an 8-pin MSOP package and supports operation from -40 °C to +85 °C.

Digital Potentiometers Feature Summary

• Single digital potentiometer with 50 kΩ total resistance and 32-tap resolution
• Nonvolatile memory retains wiper position upon power cycle
• Increment/Decrement (Up/Down) serial control interface
• Buffered wiper output for improved drive capability

Digital Potentiometers Applications

• Automated gain control in instrumentation systems
• Volume or tone control in audio equipment
• Calibration adjustments for sensor signal conditioning
• Voltage reference trimming in measurement devices

Digital Potentiometers Procurement Notes

Verify the specific suffix against official datasheets, as variations such as 'T3' indicate tape-and-reel packaging while others may denote cut tape. Confirm RoHS compliance status and lead-free specifications directly with the manufacturer or authorized distributors before procurement.

Digital Potentiometers Selection Notes

Select this component when a buffered wiper output is required to drive low-impedance loads without affecting the internal resistive array. Ensure the application requires nonvolatile storage to maintain calibration settings after power interruptions. Verify that the 50 kΩ resistance and 32-step resolution align with the system's precision requirements.

Digital Potentiometers Part Context

This part belongs to the CAT5112 family of 32-tap digital potentiometers. It is functionally similar to the CAT5114 but distinguished by its buffered wiper output. Variants exist with different resistance values (e.g., 10 kΩ) and packages (e.g., SOIC-8), sharing the same core architecture and control logic.

Digital Potentiometers Replacement Considerations

The CAT5114 series serves as a primary alternative; however, it lacks the buffered wiper feature found in the CAT5112. Direct pin-compatible substitutes within the same family include other CAT5112 variants with differing resistance values.
