LT6656BCDC-3.3#TRPBF

Voltage Reference Overview

The LT6656BCDC-3.3#TRPBF is a precision series voltage reference manufactured by Analog Devices Inc., featuring a fixed output of 3.3V in a 6-lead DFN package. It operates within a specified temperature range of 0°C to 70°C and functions from –55°C to 125°C. The device draws less than 1µA of supply current, offers an initial accuracy of 0.1%, and exhibits a maximum temperature drift of 20ppm/°C. It supports up to 5mA of output drive with a dropout voltage as low as 10mV and accepts input voltages up to 18V.

Voltage Reference Feature Summary

• Ultralow power consumption with supply current under 1µA for extended battery life
• Low dropout operation allowing functionality with minimal voltage difference between input and output
• High stability with defined initial accuracy and temperature coefficient specifications
• Robust protection features including reverse input/output handling and indefinite short-circuit duration

Voltage Reference Applications

• Precision A/D and D/A converters
• Portable gas monitors
• Battery- or solar-powered systems
• Micropower remote sensing

Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the BCDC designation corresponds to the B-grade accuracy (0.1%) and DC package type (DFN). Ensure the supplier provides documentation confirming the commercial temperature grade (0°C to 70°C) matches your system requirements, as industrial grades are available with different suffixes.

Voltage Reference Selection Notes

Select this component when a compact surface-mount solution is required for low-power applications. The B-grade specification suits designs where 0.1% initial accuracy and 20ppm/°C drift are acceptable. Consider the DFN package dimensions for PCB layout constraints. Verify that the 0°C to 70°C operating range aligns with the environmental conditions of the final assembly.

Voltage Reference Part Context

This part belongs to the LT6656 family of 1µA precision series voltage references. The family includes variants with different output voltages, accuracy grades (A and B), and packages (TSOT-23, DFN, LS8). The LT6656 is designed to replace shunt references in portable instrumentation to reduce quiescent current and extend battery life while maintaining high precision.

Voltage Reference Replacement Considerations

LT6656BCDC-3.3#TRMPBF: Same electrical characteristics and package, but supplied in mini-tape and reel instead of standard tape and reel.
