LT6656BCS6-2.048#TRMPBF

Voltage Reference Overview

The LT6656BCS6-2.048#TRMPBF is a precision series voltage reference manufactured by Analog Devices Inc., featuring a fixed output of 2.048V. It operates within an industrial temperature range of –40°C to 85°C and offers an initial accuracy of 0.1% with a maximum temperature coefficient of 20ppm/°C. The device draws less than 1µA of supply current, enabling extended battery life in portable applications. It supports a wide input voltage range up to 18V and provides a minimum output drive current of 5mA.

Voltage Reference Feature Summary

• Ultralow supply current consumption for battery-powered instrumentation
• High accuracy with specified initial tolerance and low temperature drift
• Capable of sourcing up to 5mA of output drive current
• Operates with minimal dropout voltage relative to the output level

Voltage Reference Applications

• Precision A/D and D/A converters
• Portable gas monitors
• Battery- or solar-powered systems
• Precision regulators
• Low voltage signal processing

Voltage Reference Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel packaging when ordering. Confirm that the B grade designation corresponds to the required 0.1% accuracy and 20ppm/°C drift specifications for your design. Ensure the industrial temperature rating meets environmental requirements. Check manufacturer documentation for lead-free finish compliance and RoHS status prior to procurement.

Voltage Reference Selection Notes

Select this component when a compact, low-power reference is needed for ADC excitation or signal conditioning. The 2.048V option is suitable for standard data acquisition systems. Consider the SOT-23 package for space-constrained PCB layouts. Verify that the load regulation and noise performance meet system sensitivity requirements compared to higher-grade alternatives.

Voltage Reference Part Context

This part belongs to the LT6656 family of 1µA precision series voltage references. It shares core architectural features with other variants in the series, differing primarily in output voltage options, accuracy grades (A vs. B), and package types such as TSOT-23, DFN, and LS8. The BC prefix denotes the commercial temperature range variant, though the datasheet specifies industrial availability for this configuration.
