LT6656ACDC-3.3#TRMPBF

Voltage Reference Overview

The LT6656ACDC-3.3#TRMPBF is a precision series voltage reference manufactured by Analog Devices Inc., featuring a fixed output voltage of 3.3V. It operates within an industrial temperature range of –40°C to 85°C and is housed in a 6-lead (2mm × 2mm) plastic DFN package. The device draws less than 1µA of supply current, with a typical value of 1µA at maximum limits. Initial accuracy is specified at 0.1%, and the temperature coefficient is 20ppm/°C. It supports up to 5mA of output drive current with a dropout voltage as low as 10mV.

Voltage Reference Procurement Notes

Verify that the specific part number matches the required voltage option, grade, and package type. Confirm the suffix indicates tape and reel mini packaging. Ensure the component meets the specified industrial temperature range requirements for your application environment before finalizing procurement.

Voltage Reference Selection Notes

Select this component when a stable 3.3V reference is needed with strict power constraints. The A-grade specification ensures tighter tolerance compared to B-grade options. Consider the DFN package for space-constrained designs requiring surface mount assembly. Verify that the load current requirements do not exceed the 5mA sourcing capability.

Voltage Reference Part Context

This component belongs to the LT6656 family of micropower precision voltage references. The ACDC designation identifies it as the A-grade version with 0.1% accuracy and 20ppm/°C drift, packaged in a 6-lead DFN format. The #TRMPBF suffix denotes the specific tape and reel mini packaging configuration.
