AD680JRZ-REEL7

Overview

The AD680JRZ-REEL7 is a laser-trimmed band gap voltage reference providing a fixed 2.5 V output from input voltages between 4.5 V and 36 V. It operates with a maximum quiescent current of 250 μA and features an initial accuracy of ±10 mV (±0.4%). The device exhibits a temperature coefficient of 25 ppm/°C over the 0°C to 70°C range, with low noise characteristics of 10 μV p-p from 0.1 Hz to 10 Hz. Packaged in an 8-lead SOIC, it includes a dedicated temperature output pin.

Feature Summary

• Laser trimmed for high initial accuracy and low temperature drift without external components
• Low quiescent current operation suitable for power-sensitive applications
• Integrated temperature output pin enabling configuration as a temperature transducer

Applications

• Reference for data converters requiring external precision voltage sources
• Portable equipment power supplies
• Hand-held battery-operated meters

Procurement Notes

Verify that the specific ordering suffix matches the required reel quantity and package variant. Confirm the grade designation corresponds to the necessary operating temperature range and accuracy specifications before procurement. Ensure compatibility with existing PCB footprints for the 8-lead SOIC package.

Selection Notes

Select this component when a stable 2.5 V reference is needed with minimal supply current consumption. The 8-lead SOIC package supports surface-mount assembly. Verify that the input voltage remains within the specified 4.5 V to 36 V range to ensure proper regulation and performance stability.

Part Context

The AD680 series comprises complete band gap voltage references available in multiple grades and packages. The JRZ variant specifically denotes the industrial temperature range version housed in a surface-mount SOIC package. This family offers a cost-effective alternative to traditional two-terminal references while maintaining superior precision and stability.

Replacement Considerations

AD680JR is a direct substitute part number.
