LT6656ACS6-3.3#TRMPBF

Voltage Reference Overview

The LT6656ACS6-3.3#TRMPBF is a precision series voltage reference manufactured by Analog Devices Inc., featuring a fixed output of 3.3V with an initial accuracy of ±0.05% and a maximum temperature coefficient of 10ppm/°C. It operates within a supply voltage range of 3.5V to 18V, drawing a typical supply current of 850nA. The device provides a minimum output drive current of 5mA and requires a minimum output capacitance of 1µF for stability. It is housed in a 6-lead TSOT-23 package and is specified for operation from -40°C to 85°C.

Voltage Reference Feature Summary

• Ultralow supply current consumption suitable for battery-powered applications
• High accuracy with low temperature drift characteristics
• Capable of supplying 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 #TRMPBF indicates tape and reel packaging when sourcing. Confirm the 'A' grade designation corresponds to the required 0.05% accuracy and 10ppm/°C drift specifications. Ensure the component matches the industrial temperature range requirements for your application environment.

Voltage Reference Selection Notes

Select this part for designs requiring high precision in a compact surface-mount package. The ultralow quiescent current makes it ideal for extending battery life in portable instrumentation. Consider the 5mA drive capability if the reference also serves as a supply voltage for low-power ADCs.

Voltage Reference Part Context

This component belongs to the LT6656 family of 1µA precision series voltage references. It is available in multiple output voltages and packages, including TSOT-23, DFN, and LS8. The 'S6' suffix denotes the 6-lead plastic TSOT-23 package, while 'AC' specifies the commercial temperature grade and accuracy level.

Voltage Reference Replacement Considerations

LT6656AIS6-3.3#TRMPBF offers the same electrical performance but covers the extended industrial temperature range (-40°C to 85°C) compared to the commercial grade.
