CAT5118TBI-10-T

Digital Potentiometers Overview

The CAT5118TBI-10-T is a single-channel digital potentiometer from the MiniPot family, manufactured by onsemi. It features a linear taper with 32 tap positions and a nominal resistance of 10 kOhms. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V, with a typical operating current of 25 uA. It utilizes a 2-wire serial up/down interface for control. The component is housed in a space-saving SOT-23-5 package and supports an operating temperature range from -40°C to +85°C. The wiper memory is volatile.

• Gain adjustment in signal conditioning
• Line impedance matching
• Replacement for mechanical potentiometers

Digital Potentiometers Procurement Notes

Verify the specific suffix 'T' against official datasheets to confirm tape-and-reel packaging specifications. Confirm RoHS compliance status through the manufacturer's latest documentation. Check for end-of-life notifications or obsolescence notices from onsemi prior to procurement planning.

Digital Potentiometers Selection Notes

Select this component when a compact, digitally controlled variable resistor is required. Ensure the application does not require non-volatile memory retention, as this model uses volatile storage. Verify that the 10 kOhms resistance value and 32-step resolution meet the circuit requirements. The SOT-23-5 package is suitable for space-constrained PCB designs.

Digital Potentiometers Part Context

This part belongs to the CAT511x series of 32-tap digital potentiometers. The 'CAT5118' designation indicates a potentiometer configuration, distinguishing it from variable resistor variants like the CAT5119. The 'TBI' suffix typically denotes the SOT-23 package and industrial temperature grade, while '10' specifies the 10 kOhms resistance value.

Digital Potentiometers Replacement Considerations

Direct pin-compatible replacements within the same family include CAT5110TBI-10-T (potentiometer) and CAT5119TBI-10-T (variable resistor). For different resistance values, consider CAT5118TBI-50-T (50 kOhms) or CAT5118TBI-100-T (100 kOhms). Cross-reference with other manufacturers offering 32-tap 2-wire digital potentiometers if sourcing constraints exist.
