LT6656ACS6-1.25#TRMPBF

Voltage Reference Overview

The LT6656ACS6-1.25#TRMPBF is a precision series voltage reference manufactured by Analog Devices Inc., featuring a fixed output of 1.25V with an initial accuracy of ±0.05% and a temperature coefficient of 10ppm/°C. It operates within a supply voltage range of 1.35V to 18V, drawing a typical supply current of 1µA. The device provides up to 5mA of output drive current and is housed in a 6-lead TSOT-23 package. It is specified for commercial operation from 0°C to 70°C.

Voltage Reference Feature Summary

• Ultralow supply current consumption enables extended battery life in portable applications.
• High accuracy and low drift characteristics ensure stable reference performance across temperature variations.
• Capable of operating with a supply voltage as low as 10mV above the output voltage.
• Includes reverse input and output protection for enhanced circuit robustness.

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 mini packaging when sourcing. Confirm the 'A' grade designation matches the required 0.05% accuracy and 10ppm/°C drift specifications. Ensure the commercial temperature range (0°C to 70°C) aligns with the system environment requirements before finalizing procurement.

Voltage Reference Selection Notes

Select this component for designs requiring high precision in a compact surface-mount package. The 1.25V output is suitable for driving ADCs or DACs directly. Consider the 1µA quiescent current for power-sensitive applications. Verify that the load capacitance meets the minimum requirement for stability.

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 but is distinguished by its 1.25V output, 'A' grade accuracy, and TSOT-23 packaging. It serves as a low-power alternative to shunt references in battery-operated instrumentation.

Voltage Reference Replacement Considerations

Direct substitutes include LT6656AIS6-1.25#TRMPBF for industrial temperature range (-40°C to 85°C). Other voltage options within the same package are available by changing the numeric suffix. Cross-package replacements require verifying pin compatibility and thermal characteristics.
