CAT5118SDGI-50-T3

Digital Potentiometers Overview

The CAT5118SDGI-50-T3 is a single-channel digital potentiometer from onsemi's MiniPot family. It features a 50 kΩ resistance value with 32 linear taps and operates on a 2-wire serial interface. The device supports a supply voltage range of 2.7 V to 5.5 V and consumes 25 µA of operating current. It utilizes volatile memory for wiper settings and is housed in an SC-70-6 surface-mount package, suitable for temperature ranges between -40 °C and +85 °C.

Digital Potentiometers Procurement Notes

Verify the specific suffix 'SDGI' against official onsemi documentation to confirm pinout compatibility and package dimensions. Confirm availability status as distribution listings may vary. Ensure the volatile memory characteristic aligns with system power-loss requirements.

Digital Potentiometers Selection Notes

Select this component when a compact, low-power digital potentiometer with 32 steps is required. The 50 kΩ value suits moderate impedance applications. Verify that the 2-wire interface matches the host controller's capabilities and that volatile storage meets the application's persistence needs.

Digital Potentiometers Part Context

This part belongs to the CAT5118 series of MiniPot digital potentiometers. The series offers various resistance values and interface options. The SDGI suffix typically denotes the SC-70-6 package and specific tape-and-reel packaging configuration within the product line.

Digital Potentiometers Replacement Considerations

Direct replacements include other CAT5118 variants with compatible interfaces and resistance values. Cross-reference package dimensions and pinouts before substitution. Consider CAT5119 or CAT5110 series parts if different resistance or tap counts are acceptable.
