LT6656BIDC-5#TRPBF

Overview

The LT6656BIDC-5#TRPBF is a precision series voltage reference manufactured by Analog Devices Inc. It provides a fixed output voltage of 5V with an initial accuracy of ±0.2%. The device operates within a specified temperature range of -40°C to 85°C and features a maximum temperature coefficient of 20ppm/°C. It draws a supply current of 1.5µA and can deliver up to 5mA of output drive current. The component accepts an input voltage between 5.5V and 18V and is housed in a 6-lead (2mm × 2mm) plastic DFN package.

Feature Summary

• Ultralow supply current consumption for extended battery life
• High output drive capability supporting loads up to 5mA
• Reverse input and output protection against connection errors
• Operational stability with wide range of output capacitor ESR

Applications

• Precision A/D and D/A converters
• Portable gas monitors
• Battery- or solar-powered systems
• Micropower remote sensing

Procurement Notes

Verify the specific B-grade accuracy and industrial temperature rating requirements against the application needs. Confirm the DFN package footprint matches the PCB layout. Ensure the supply voltage remains within the 5.5V to 18V range during operation. Check for any specific long-term drift requirements that may necessitate higher grade options.

Selection Notes

Select this part when a 5V reference is required with moderate accuracy and low power consumption. The B-grade offers lower initial accuracy than the A-grade but maintains stable performance over the industrial temperature range. Consider the DFN package size constraints and thermal dissipation capabilities relative to the ambient environment.

Part Context

This component belongs to the LT6656 family of precision voltage references, designed for portable instrumentation. The family includes various output voltages and packages such as TSOT-23 and LS8. The BIDC variant specifically denotes the B-grade accuracy, DC package type, 5V output, and tape-and-reel packaging format.
