LT6656BIDC-2.5#TRPBF

Voltage Reference Overview

The LT6656BIDC-2.5#TRPBF is a precision series voltage reference manufactured by Analog Devices Inc., featuring a fixed output voltage of 2.5V. 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 with an exposed pad. The device draws less than 1µA of supply current, typically 850nA, and supports a maximum input voltage of 18V. It provides an initial accuracy of 0.1% and a maximum temperature coefficient of 20ppm/°C. The component can source up to 5mA of output drive current.

Voltage Reference Feature Summary

• Ultra-low power consumption with typical supply current below 1µA
• Capable of operation with supply voltage within 10mV of the output voltage
• Includes reverse input and output protection capabilities
• Stable operation with output capacitance of 1µF or larger

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify that the ordering suffix #TRPBF corresponds to tape and reel packaging rather than tray distribution. Confirm the specific grade 'I' indicates the –40°C to 85°C industrial temperature range. Ensure the DC package designation matches the required 6-lead DFN footprint for PCB layout compatibility.

Voltage Reference Selection Notes

Select this part when a 2.5V reference is required with B-grade accuracy specifications. Consider the DFN package for space-constrained designs requiring surface mount technology. Verify that the load regulation and noise characteristics meet the requirements of the connected analog circuitry.
