CAT5191TBE-50GT3

Digital Potentiometers Overview

The CAT5191TBE-50GT3 is a single-channel digital potentiometer manufactured by onsemi. It features a resistance value of 50 kΩ with 256 adjustable taps, providing precise resistance control via an I²C serial interface. The device operates within a supply voltage range of 2.7 V to 5.5 V and consumes a typical operating current of 300 nA. Designed for surface-mount applications, it utilizes a compact SC-70 package with six pins. The component supports an operating temperature range from -40°C to +85°C and employs volatile memory to retain wiper position settings during power cycles.

Digital Potentiometers Procurement Notes

Verify the specific suffix '50GT3' against official onsemi documentation to confirm the exact resistance tolerance and tape-and-reel packaging specifications. Ensure compatibility with the target I²C clock speeds and voltage levels before finalizing procurement orders.

Digital Potentiometers Selection Notes

Select this component when a single-channel digital potentiometer with 256 steps is required. The 50 kΩ nominal resistance suits moderate impedance applications. Verify that the volatile memory characteristic aligns with the application's need to reset to a default state upon power-up.

Digital Potentiometers Part Context

This part belongs to the CAT5191 family of digital potentiometers. The base model offers a single channel, while other variants in the series may provide dual channels or different tap counts. The 'TBE' designation typically indicates the specific package type and temperature grade defined by the manufacturer.

Digital Potentiometers Replacement Considerations

Direct replacements include other onsemi CAT5191 variants with matching pinouts and electrical characteristics. Cross-manufacturer equivalents should be evaluated based on I²C protocol compatibility, resistance tolerance, and package dimensions.
