LT6656AIDC-3#TRMPBF

Voltage Reference Overview

The LT6656AIDC-3#TRMPBF is a precision series voltage reference manufactured by Analog Devices Inc. It provides a fixed output voltage of 3V with an initial accuracy of ±0.1% and a maximum temperature coefficient of 10ppm/°C. The device operates within a supply voltage range of 3.5V to 18V, drawing a typical supply current of 1µA. It features a minimum output drive current of 5mA and requires a minimum output capacitance of 1µF for stability. The component is housed in a 6-lead (2mm × 2mm) plastic DFN 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
• Low dropout voltage allowing operation with minimal headroom
• High output drive capability supporting direct connection to low power ADCs
• Reverse input and output protection against connection errors

Voltage Reference Applications

• Precision A/D and D/A converters
