LT6656BCDC-4.096#TRPBF

Voltage Reference Overview

The LT6656BCDC-4.096#TRPBF is a precision series voltage reference manufactured by Analog Devices Inc., featuring a fixed output of 4.096V in a 6-lead plastic DFN package. It operates within an industrial temperature range of –40°C to 85°C with B-grade specifications, including an initial accuracy of ±0.1% and a maximum temperature coefficient of 20ppm/°C. The device draws a typical supply current of 1µA and supports up to 5mA of output drive current. It functions with a wide input voltage range up to 18V and maintains stability with output capacitance of 1µF or greater.

Voltage Reference Procurement Notes

Verify that the specific part number matches the required B-grade accuracy and industrial temperature range. Confirm the 6-lead DFN package type aligns with the PCB footprint design. Ensure the tape and reel packaging format meets automated assembly requirements. Cross-reference the datasheet revision to confirm electrical characteristics match the design specifications.

Voltage Reference Selection Notes

Select this component when a stable 4.096V reference is needed with strict power constraints. The B-grade specification provides adequate accuracy for general-purpose applications where A-grade precision is not mandatory. Consider the DFN package size if board space is limited compared to SOT-23 options. Verify that the 20ppm/°C drift meets the system's long-term stability requirements.

Voltage Reference Part Context

This component belongs to the LT6656 family of micropower precision voltage references. The family includes various output voltages and grades (A and B) across multiple packages such as TSOT-23 and LS8. The BCDC suffix indicates the B-grade accuracy level and the specific 6-lead DFN package configuration used for surface mount applications.

Voltage Reference Replacement Considerations

LT6656ACDC-4.096#TRPBF offers the same package but with commercial temperature range and A-grade accuracy. LT6656AIS6-4.096#TRPBF provides A-grade accuracy in a TSOT-23 package. LT6656BIS6-4.096#TRMPBF is the B-grade equivalent in a TSOT-23 package.
