LT6656AIDC-3#TRPBF

Voltage Reference Overview

The LT6656AIDC-3#TRPBF is a precision series voltage reference from Analog Devices Inc. It provides a fixed output voltage of 3V with an initial accuracy of ±0.05% and a maximum temperature coefficient of 10ppm/°C. The device operates within a supply voltage range of 2.51V to 18V, drawing a typical supply current of 1µA (maximum 1.5µA). It features a minimum dropout voltage of 10mV at zero load and can source up to 5mA of output drive current. The component is housed in a 6-lead DFN package and is specified for operation over the industrial temperature range of –40°C to 85°C.

Voltage Reference Feature Summary

• Ultralow power consumption suitable for battery-operated instrumentation
• High precision with minimal temperature drift and tight initial accuracy tolerance
• Capable of driving loads up to 5mA while maintaining stable regulation
• Operates with extremely low dropout voltage relative to the output level

Voltage Reference Applications

• Precision analog-to-digital converter (ADC) reference inputs
• Portable gas monitors and handheld measurement devices
• Battery-powered or solar-powered system instrumentation
• Low voltage signal processing circuits

Voltage Reference Procurement Notes

Verify that the specific part number matches the required 3V output option and A-grade accuracy specifications. Confirm the package type corresponds to the 6-lead DFN configuration. Ensure the temperature grade aligns with the intended industrial operating environment requirements before finalizing procurement orders.

Voltage Reference Selection Notes

Select this component when design constraints require high precision combined with minimal quiescent current draw. It is appropriate for applications where the supply voltage may vary close to the output level due to its low dropout characteristic. Consider the 5mA drive capability if the reference must also serve as a local power supply for downstream components.

Voltage Reference Part Context

This component belongs to the LT6656 family of micropower precision voltage references. The family includes various output voltage options and package types such as TSOT-23 and LS8. The DC suffix indicates the plastic DFN package variant, while the IS6 suffix denotes the TSOT-23 package. The A grade specifies the tighter performance tolerances compared to the B grade.
