LT6656BIS6-2.5#TRPBF

Voltage Reference Overview

The LT6656BIS6-2.5#TRPBF is a precision series voltage reference manufactured by Analog Devices Inc., featuring an output voltage of 2.5V. It operates within the industrial temperature range of –40°C to +85°C and is housed in a 6-lead plastic TSOT-23 package. The device offers an initial accuracy of 0.1% and a maximum temperature coefficient of 20ppm/°C. It draws less than 1µA of supply current and can operate with a supply voltage as low as 10mV above the output voltage, supporting a wide input range up to 18V.

Voltage Reference Feature Summary

• Ultralow supply current consumption for extended battery life
• High accuracy with low temperature drift characteristics
• Capable of sourcing up to 5mA of output drive current
• Operates with minimal dropout voltage relative to output level

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% initial accuracy and 20ppm/°C temperature coefficient specifications. Ensure the S6 package type matches the target PCB footprint requirements for the 6-lead TSOT-23 form factor.

Voltage Reference Selection Notes

Select this component for applications requiring high precision in a compact surface-mount package. The B grade provides a balance of cost and performance suitable for industrial environments. 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 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 IS6 suffix denotes the industrial temperature range and TSOT-23 package configuration.

Voltage Reference Replacement Considerations

LT6656AIS6-2.5#TRPBF: Offers higher accuracy (0.05%) and lower drift (10ppm/°C) in the same package.
