AD780BR-REEL

Overview

The AD780BR-REEL is an ultrahigh precision bandgap reference voltage IC manufactured by Analog Devices Inc. It provides a programmable output of either 2.5 V or 3.0 V from input voltages ranging between 4.0 V and 36 V. The device features a maximum temperature coefficient of 3 ppm/°C and a maximum initial error of ±1 mV at the selected output voltage. It operates with a maximum quiescent current of 1 mA and supports a maximum shunt current of 10 mA. The component is housed in an SOIC-8 package and is supplied in reel packaging.

Feature Summary

• Pin-programmable selection between 2.5 V and 3.0 V output levels
• Ultralow drift characteristics with a maximum temperature coefficient of 3 ppm/°C
• Low noise performance suitable for high-resolution data converter applications
• Capability to drive any value of output capacitance without stability issues

Applications

• Enhancing performance of high-resolution analog-to-digital converters (ADCs)
• Enhancing performance of high-resolution digital-to-analog converters (DACs)
• General-purpose precision reference applications requiring low headroom operation

Procurement Notes

Verify the specific suffix configuration against the manufacturer's official documentation, as ordering suffixes may indicate variations in packaging or environmental compliance. Confirm that the required output voltage setting matches the pin-programming requirements specified in the datasheet. Ensure the input voltage range remains within the 4.0 V to 36 V limits during system design integration.

Selection Notes

Select this component when ultrahigh precision and low temperature drift are critical for signal chain accuracy. The ability to boost dynamic range by providing a 3.0 V output from a 5.0 V input makes it suitable for systems where standard 2.5 V references are insufficient. Consider the low quiescent current and noise specifications for battery-powered or sensitive measurement instruments.

Part Context

The AD780 series represents Analog Devices' ultrahigh precision bandgap reference family. This specific part utilizes a unique low headroom design to facilitate higher output voltages from lower input supplies. It serves as a plug-in upgrade for existing reference designs, offering improved accuracy and noise performance compared to older generation voltage references.
