LT6656BCS6-4.096#TRMPBF

Voltage Reference Overview

The LT6656BCS6-4.096#TRMPBF is a precision series voltage reference manufactured by Analog Devices Inc., housed in a 6-lead plastic TSOT-23 package. It provides a fixed output voltage of 4.096V with an initial accuracy of 0.1% and a maximum temperature coefficient of 20ppm/°C. The device operates within a supply voltage range up to 18V, drawing a typical supply current of 850nA. It supports a minimum output drive current of 5mA and requires a minimum output capacitance of 1µF for stable operation.

Voltage Reference Feature Summary

• Ultralow supply current consumption suitable for battery-powered applications
• High output drive capability allowing use as both supply and reference
• Reverse input and output protection against connection errors
• Operational stability with a wide range of output capacitor ESR values

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 #TRMPBF indicates tape and reel packaging when sourcing components. Confirm that the B grade designation corresponds to the required 0.1% initial accuracy and 20ppm/°C temperature coefficient specifications for your design constraints. Ensure the industrial temperature range coverage meets your operational environment requirements.

Voltage Reference Selection Notes

Select this component when low quiescent current is critical alongside moderate precision requirements. The B grade offers a balance between cost and performance compared to the higher accuracy A grade. Consider the TSOT-23 package size if board space is limited, while ensuring the 5mA drive current suffices for the connected load without exceeding thermal limits.

Voltage Reference Part Context

This part belongs to the LT6656 family of micro power precision voltage references. The family includes variants with different output voltages, accuracy grades (A and B), and packages such as DFN and LS8. The BC prefix denotes the B grade accuracy level and the S6 TSOT-23 package type, distinguishing it from other configurations within the same product line.
