CAT5119TBI-00-GT3

Digital Potentiometers Overview

The CAT5119TBI-00-GT3 is a single-channel digital potentiometer from the CAT5119 series manufactured by onsemi. It features a 100 kΩ resistance value with a linear taper and 32 programmable taps. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V and draws a typical operating current of 25 µA. It utilizes a 2-wire serial interface for up/down control and is housed in a compact SC-70-6 surface-mount package. The component functions as a variable resistor with volatile wiper memory.

Digital Potentiometers Feature Summary

• Single digital potentiometer with 100 kΩ nominal resistance and linear taper
• 32-tap resolution controlled via a 2-wire serial (up/down) interface
• Low power consumption with 25 µA operating current and 2.7 V to 5.5 V supply range
• Compact SC-70-6 SMD package suitable for space-constrained designs

Digital Potentiometers Applications

• Mechanical potentiometer replacement in embedded systems
• Gain adjustment in signal conditioning circuits
• Line impedance matching applications

Digital Potentiometers Procurement Notes

Verify the specific suffix 'TBI-00-GT3' against the manufacturer's official datasheet to confirm the 100 kΩ resistance value and SC-70-6 packaging. Ensure compatibility with the required 2-wire serial protocol and check for any RoHS compliance documentation relevant to the manufacturing batch.

Digital Potentiometers Selection Notes

Select this component when a volatile, single-channel digital variable resistor is required. The 100 kΩ value and 32-tap resolution are fixed specifications for this part number. Compare against the CAT5110 or CAT5125 if non-volatile memory or different resistance values are needed, as these variants belong to the same family but differ in internal architecture and pinout configurations.

Digital Potentiometers Part Context

This part belongs to the CAT511x MiniPot family of digitally programmable potentiometers. These devices are designed to replace mechanical potentiometers in applications requiring digital control of resistance. The CAT5119 variant specifically serves as a variable resistor rather than a potentiometer configuration found in other family members like the CAT5110.
