LT6656ACDC-5#TRMPBF

Voltage Reference Overview

The LT6656ACDC-5#TRMPBF is a precision series voltage reference manufactured by Analog Devices Inc. It provides a fixed output voltage of 5V with an initial accuracy of ±0.1% and a maximum temperature coefficient of 20ppm/°C. The device operates within a supply voltage range of 2.5V 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 commercial operation from 0°C to 70°C.

Voltage Reference Feature Summary

• Ultralow supply current consumption suitable for battery-powered applications

Voltage Reference Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel packaging when sourcing. Confirm the AC grade designation corresponds to the required 0.1% initial accuracy and 20ppm/°C temperature coefficient specifications. Ensure the DC package type matches the PCB footprint requirements. Check that the commercial temperature range meets the application environment constraints.

Voltage Reference Selection Notes

Select this part for applications requiring a 5V reference with moderate precision and low power consumption. The AC grade offers 0.1% accuracy, which is sufficient for general instrumentation but less precise than the AIS6 variants. Consider the DFN package size for space-constrained designs. Verify that the 20ppm/°C drift meets system tolerance requirements compared to higher-grade alternatives.

Voltage Reference Part Context

This component belongs to the LT6656 family of tiny precision voltage references. The family includes various output voltages and grades (A and B) across different packages such as TSOT-23, DFN, and LS8. The ACDC-5 variant specifically denotes the 5V output option in the DFN package with commercial temperature grading.
