CAT5114ZI-50-TE13

Digital Potentiometers Overview

The CAT5114ZI-50-TE13 is a single-channel digital potentiometer IC manufactured by onsemi. It features a 50 kOhm resistance value with a linear taper and 32 tap positions. The device utilizes a nonvolatile memory architecture to retain the wiper setting during power loss, automatically restoring it upon power return. Control is managed via a serial three-wire interface (CS, U/D, INC). It operates within a supply voltage range of 2.5 V to 6 V and supports an operating temperature range from -40°C to +85°C. The component is housed in an 8-pin SOIC surface-mount package.

Digital Potentiometers Feature Summary

• Nonvolatile memory retains wiper position after power-down

• Serial 3-wire control interface (CS, U/D, INC)
• Linear taper with 20% tolerance

Digital Potentiometers Applications

• Automated adjustments on high-volume production lines
• Equipment requiring periodic adjustment in hazardous or remote environments
• Electronic replacement for mechanical potentiometers and trim pots

Digital Potentiometers Procurement Notes

Verify current availability status as this component may be subject to end-of-life restrictions. Confirm RoHS compliance details through official datasheets before procurement. Ensure the specific TE13 suffix corresponds to the required tape-and-reel packaging configuration for your assembly process.

Digital Potentiometers Selection Notes

Select this part when a single-channel digital solution with nonvolatile storage is required. The 32-tap resolution suits applications where coarse-to-medium adjustment precision is sufficient. Verify that the 3-wire serial interface aligns with the system's microcontroller or logic capabilities, noting that it differs from I2C-compatible devices.

Digital Potentiometers Part Context

This component belongs to the CAT5114 series of digital potentiometers. It serves as a solid-state alternative to traditional mechanical potentiometers, offering improved reliability and automation compatibility. The ZI suffix typically denotes the SOIC-8 package variant within this product line.

Digital Potentiometers Replacement Considerations

Direct replacements must match the 32-tap count, 50 kOhm resistance, and 3-wire serial interface. Devices like the CAT5114LI-50-G offer similar electrical characteristics but differ in package type (PDIP vs. SOIC). Ensure pinout compatibility when substituting across package variations.
