CAT5110TBI-10-T

Digital Potentiometers Overview

The CAT5110TBI-10-T is a single-channel digital potentiometer IC from onsemi, featuring a 10 kOhms resistance value and linear taper. It provides 32 tap positions controlled via a 2-wire serial interface. The device operates within a supply voltage range of 2.7 V to 5.5 V with a typical current consumption of 25 uA. It utilizes volatile brush memory and functions across an industrial temperature range of -40°C to +85°C. Packaged in a compact SOT-23-6 surface-mount format, it serves as a solid-state replacement for mechanical potentiometers.

Digital Potentiometers Feature Summary

• Single-potentiometer configuration with 10 kOhms nominal resistance and linear taper
• 32-tap resolution controlled by a simple 2-wire up/down serial interface
• Low power operation with 25 uA supply current at 2.7 V to 5.5 V
• Compact SOT-23-6 package suitable for space-constrained PCB designs

Digital Potentiometers Applications

• Volume control and gain adjustment in audio circuits
• Programmable voltage reference generation
• Sensor biasing and calibration adjustments
• Light dimming and LED brightness control

Digital Potentiometers Procurement Notes

Verify the specific suffix 'T' against official documentation to confirm tape-and-reel packaging quantities. Confirm end-of-life status through manufacturer notifications or PCN documents prior to design finalization. Ensure compatibility with existing 2-wire serial protocols during integration.

Digital Potentiometers Selection Notes

Select this component when a linear response curve is required for precise resistance stepping. The 32-tap resolution offers a balance between control granularity and interface simplicity. Verify that the 10 kOhms total resistance aligns with the target circuit's impedance requirements and power dissipation limits.

Digital Potentiometers Part Context

This part belongs to the CAT5110 family of MiniPot digital potentiometers. It shares architectural similarities with other CAT51xx series devices but is distinct in its specific resistance value, tap count, and interface type compared to non-volatile or higher-resolution variants.

Digital Potentiometers Replacement Considerations

Direct pin-compatible replacements may include other CAT5110 variants with different resistance values (e.g., 50k, 100k) if electrical parameters allow. Cross-reference with CAT5120 series for similar functionality but verify interface differences.
