CAT5110TBI-10GT3

Digital Potentiometers Overview

The CAT5110TBI-10GT3 is a single-channel digital potentiometer IC from the onsemi CAT5110 series. It features a 10 kOhms resistance value with a linear taper and 32 taps for resolution. The device operates within a supply voltage range of 2.7 V to 5.5 V, consuming 25 uA of current. It utilizes a 2-wire serial interface for control and has volatile brush memory. The component is housed in an SMD/SMT package, specifically SC-70-6, and supports an operating temperature range from -40°C to +85°C.

Digital Potentiometers Feature Summary

• Single digital potentiometer with 10 kOhms resistance and linear taper
• 32-tap resolution controlled via 2-wire serial interface
• Low power consumption of 25 uA with 2.7 V to 5.5 V supply range
• Volatile wiper memory retains settings only during power

Digital Potentiometers Applications

• Volume control in audio equipment
• Gain adjustment in signal conditioning circuits
• Voltage reference trimming
• System calibration where power-off state reset is acceptable

Digital Potentiometers Procurement Notes

The CAT5110TBI-10GT3 is listed as End-of-Life (EOL) by onsemi. Verification of availability requires checking distributor stock or obsolete inventory channels. Designers should confirm the specific manufacturing date code and ensure compliance with RoHS standards before procurement. Lead times are not applicable due to discontinued status.

Digital Potentiometers Selection Notes

Select this component when a low-pin-count, single-channel digital potentiometer is required for applications tolerant of volatile memory. The 10 kOhms value suits moderate impedance circuits. For designs requiring non-volatile storage of the wiper position after power loss, the CAT5113 series should be considered instead. Ensure the 2-wire interface compatibility with the host microcontroller.

Digital Potentiometers Part Context

This part belongs to the CAT5110 family of 32-tap digital potentiometers. Variants in this series differ primarily by resistance values (e.g., 50 kOhms) and package types. The 'TBI' suffix typically denotes the SC-70-6 package and 10 kOhms resistance, while 'GT3' indicates tape and reel packaging. Other family members include variable resistor configurations like the CAT5118.

Digital Potentiometers Replacement Considerations

Publicly confirmed substitutes include the CAT5110SDI-10GT3, which shares identical electrical specifications but may differ in packaging details or manufacturing lot. The CAT5110TBI-50-T3 is a similar device with 50 kOhms resistance. No direct cross-manufacturer equivalents are verified in the provided source data.
