LT6656ACDC-2.5#TRMPBF

Voltage Reference Overview

The LT6656ACDC-2.5#TRMPBF is a precision series voltage reference from Analog Devices, offering a fixed output of 2.5V with an initial accuracy of 0.1% and a temperature coefficient of 20ppm/°C. It operates within a specified commercial temperature range of 0°C to 70°C and functions over -55°C to 125°C. The device draws less than 1µA of supply current and supports up to 5mA of output drive current. It accepts input voltages up to 18V and includes reverse input/output protection. Packaged in a 6-lead (2mm × 2mm) plastic DFN, it requires a minimum 1µF output capacitor for stability.

Voltage Reference Feature Summary

Voltage Reference Procurement Notes

Verify the specific suffix ACDC-2.5 corresponds to the required 2.5V output, 0.1% accuracy, and 20ppm/°C drift grade. Confirm the DC package denotes the 6-lead DFN form factor. Ensure the TRMPBF suffix matches the intended tape and reel packaging configuration for automated assembly processes.

Voltage Reference Selection Notes

Select this component when low power consumption is critical alongside moderate precision requirements. The 2.5V option provides a standard reference level suitable for many ADCs. Consider the 0.1% accuracy and 20ppm/°C drift specifications against stricter A-grade alternatives if higher precision is needed. Verify that the 0°C to 70°C commercial range meets the application's environmental constraints.
