LT6656BIS6-3#TRPBF

Voltage Reference Overview

The LT6656BIS6-3#TRPBF is a precision series voltage reference manufactured by Analog Devices Inc. It provides a fixed output voltage of 3V with an initial accuracy of ±0.1% and a maximum temperature coefficient of 20ppm/°C. The device operates within an industrial temperature range of –40°C to 85°C and functions over an extended range of –55°C to 125°C. It draws a typical supply current of 1µA, with a minimum of 850nA, and supports a maximum input voltage of 18V. The component is housed in a 6-lead plastic TSOT-23 package.

Voltage Reference Feature Summary

• Ultralow supply current consumption suitable for battery-powered applications
• High accuracy with specified initial error and low temperature drift
• Capable of sourcing up to 5mA of output drive current
• Operates with a dropout voltage as low as 10mV

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 ordering. Confirm 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 for RoHS compliance status on the latest datasheet revision before finalizing procurement.

Voltage Reference Selection Notes

Select this part when a fixed 3V reference is needed with moderate precision in a compact surface-mount package. The B grade offers a balance between cost and performance compared to the higher precision A grade. Consider the 1µA quiescent current for power-sensitive designs. Verify that the 5mA output drive capability meets the load requirements of the connected circuitry.

Voltage Reference Part Context

This component belongs to the LT6656 family of 1µA precision series voltage references. The family includes various output voltage options and packages such as DFN and LS8. The S6 suffix denotes the 6-lead TSOT-23 package. The IS6 suffix indicates the industrial temperature grade. This specific variant is optimized for general-purpose instrumentation where size and power efficiency are critical.

Voltage Reference Replacement Considerations

LT6656BIS6-3#TRMPBF is a verified substitute offering identical electrical characteristics but supplied in mini-tape and reel packaging instead of standard tape and reel.
