LT6656ACDC-5#TRPBF

Voltage Reference Overview

The LT6656ACDC-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 ±0.1%. The device features a maximum temperature coefficient of 20ppm/°C and draws a supply current of 1.5µA. It operates within a specified temperature range of 0°C to 70°C and can withstand input voltages up to 18V. The component is housed in a 6-lead (2mm × 2mm) plastic DFN package.

Voltage Reference Feature Summary

• Ultralow supply current consumption for extended battery life
• Low dropout operation allowing supply voltage proximity to output
• High output drive capability supporting low power ADCs
• Reverse input and output protection

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 the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the AC grade designation corresponds to the required 0.1% initial accuracy and 20ppm/°C temperature coefficient specifications. Ensure the commercial temperature range of 0°C to 70°C meets the application requirements, as industrial grades are available in other part numbers.

Voltage Reference Selection Notes

Select this component for applications requiring a stable 5V reference with minimal quiescent current draw. The DFN package offers a compact footprint suitable for space-constrained designs. Consider the 20ppm/°C drift specification against system accuracy requirements. Verify that the 18V maximum input voltage rating accommodates the highest expected supply rail.

Voltage Reference Part Context

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

Voltage Reference Replacement Considerations

LT6656BCDC-5#TRPBF: Offers 0.2% accuracy and 20ppm/°C drift in the same package. LT6656AIDC-5#TRPBF: Provides 0.1% accuracy but with improved 10ppm/°C drift and industrial temperature range.
