AD780BR-REEL7

Overview

The AD780BR-REEL7 is a series precision voltage reference IC manufactured by Analog Devices Inc. It provides stable output voltages of 2.5 V and 3 V. The device features a temperature coefficient of 3 PPM/C, ensuring high stability across operating conditions. It supports a maximum shunt current of 10 mA and operates within a temperature range of -40°C to +85°C. The component is housed in an SOIC-8 package and is supplied in reel packaging.

Feature Summary

• Provides ultrahigh precision bandgap reference outputs
• Features low temperature coefficient for thermal stability
• Supports single-supply operation with wide input voltage range

Applications

• Precision data acquisition systems
• High-resolution analog-to-digital converter references
• Instrumentation signal conditioning circuits

Procurement Notes

Verify the specific suffix REEL7 against official documentation to confirm packaging format and tape specifications. Confirm RoHS compliance status as indicated in current datasheets, noting that some listings may show non-compliant variants. Check for End-of-Life notices or discontinuance announcements from Analog Devices prior to procurement planning.

Selection Notes

Select this component when a fixed 2.5 V or 3 V reference with 3 PPM/C drift is required. Ensure the SOIC-8 package fits the board layout constraints. Verify that the 10 mA load capability meets the system's reference current demands. Compare against the AD780ARZ variant if wider industrial temperature ranges are needed.

Part Context

This part belongs to the AD780 family of precision voltage references. It shares core architectural similarities with other members like the AD780ARZ but differs in initial accuracy and temperature grade. The BR designation typically indicates a specific performance bin or temperature range compared to the ARZ variant.

Replacement Considerations

The AD780ARZ-REEL7 is a documented alternative within the same family, offering different accuracy and temperature specifications.
