CAT5110TBI-00-T3

Digital Potentiometers Overview

The CAT5110TBI-00-T3 is a 32-tap digital potentiometer from onsemi, configured for variable resistance applications. It operates on a single supply voltage ranging from 2.7 V to 5.5 V and features an ultra-low standby current of 0.3 µA. The device utilizes a 2-wire up/down serial interface for wiper position control, ensuring glitchless switching between resistor taps. It includes power-on reset functionality that sets the wiper to midscale upon initialization. The component is housed in a space-saving SOT-23 package and offers end-to-end resistance values of 10 kΩ, 50 kΩ, or 100 kΩ, with the '-00' suffix indicating the 100 kΩ variant.

Digital Potentiometers Procurement Notes

Verify the specific ordering suffixes against the manufacturer's official documentation to ensure correct package type (SOT-23) and resistance value (100 kΩ). Confirm RoHS compliance status as per the latest datasheet revision. Check for any availability notes regarding specific resistance variants within the CAT5110 family, as some may require factory contact.

Digital Potentiometers Selection Notes

Select this component when a digitally controlled variable resistor is required with low power consumption. Ensure the system voltage falls within the 2.7 V to 5.5 V range. Verify that the 32-tap resolution meets the application's precision requirements. Consider the SOT-23 package dimensions if board space is limited. Compare wiper resistance specifications if low resistance paths are critical for signal integrity.

Digital Potentiometers Part Context

This part belongs to the CAT5110/18/19/23/24/25 family of 32-tap digital potentiometers. While the CAT5110 is configured as a potentiometer, the CAT5110TBI-00-T3 specifically denotes the 100 kΩ version in an SOT-23-6 package. Other family members like CAT5118 and CAT5119 are configured as variable resistors with different pinouts. The 'T3' suffix indicates tape and reel packaging.

Digital Potentiometers Replacement Considerations

Direct replacements within the same family include other CAT5110 variants with different resistance values (e.g., CAT5110TBI-10-T3 for 10 kΩ). Cross-family replacements such as CAT5125 offer similar functionality but may have different wiper resistance characteristics. Verify pin compatibility and interface timing requirements before substituting.
