LT6656ACDC-3.3#TRPBF

Voltage Reference Overview

The LT6656ACDC-3.3#TRPBF is a precision series voltage reference with a fixed output of 3.3V, housed in a 6-lead DFN package. It features an initial accuracy of 0.1% and a maximum temperature coefficient of 20ppm/°C. The device draws less than 1µA of supply current and supports a minimum dropout voltage of 10mV at zero load. It provides a minimum output drive current of 5mA with line regulation of 40ppm/V and load regulation of 175ppm/mA. The component operates within a specified commercial temperature range of 0°C to 70°C.

Voltage Reference Feature Summary

• Ultralow power consumption suitable for battery-operated instrumentation
• High precision stability with low temperature drift characteristics
• Capable of sourcing up to 5mA while maintaining tight regulation

Voltage Reference Applications

• Precision analog-to-digital converter (ADC) voltage references
• Portable gas monitors and handheld instruments
• Battery-powered or solar-powered measurement systems

Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm that the ACDC designation corresponds to the 0°C to 70°C commercial temperature grade and the 0.1% accuracy class required for your design specifications before finalizing procurement.

Voltage Reference Selection Notes

Select this part when a fixed 3.3V reference is needed with minimal quiescent current draw. Ensure the application requires the 0.1% initial accuracy and 20ppm/°C drift limits defined for the 'C' grade. Verify that the 6-lead DFN footprint fits the PCB layout constraints.

Voltage Reference Part Context

This component belongs to the LT6656 family of micro-power precision voltage references manufactured by Analog Devices Inc. The family includes various output voltages and packages, such as TSOT-23 and LS8, offering different trade-offs between size, stability, and operating temperature ranges.

Voltage Reference Replacement Considerations

LT6656BCDC-3.3#TRPBF offers identical electrical performance but is rated for the industrial temperature range of -40°C to 85°C instead of the commercial range.
