AD584SH/883B

Voltage Reference Overview

The AD584SH/883B is a pin-programmable precision voltage reference housed in an 8-pin TO-99 metal can. It offers selectable outputs of 10.000 V, 7.500 V, 5.000 V, and 2.500 V without external components. The device operates within a supply range of 4.5 V to 30 V and features a maximum temperature coefficient of 30 ppm/°C over the -55°C to +125°C range. Initial accuracy is ±0.30% (±30 mV at 10 V). It includes a strobe terminal for power control and supports MIL-STD-883 compliance.

Voltage Reference Feature Summary

• Pin-programmable selection of four standard output voltages without external components
• Laser-trimmed for high initial accuracy and low temperature drift
• Integrated strobe terminal allows zeroing the output and reducing quiescent current
• Capable of sourcing or sinking current with short-circuit protection

Voltage Reference Applications

• Reference for 8-, 10-, or 12-bit digital-to-analog converters
• Reference for analog-to-digital converters up to 14-bit accuracy
• Precision high-current supply configurations using external transistors
• Negative reference generation in two-terminal Zener mode

Voltage Reference Procurement Notes

Verify that the component matches the specific AD584SH/883B designation to ensure MIL-STD-883 compliance and the correct S-grade temperature range. Confirm the package type is the 8-pin TO-99 metal header. Check datasheet revisions for any updates to electrical specifications or ordering information before finalizing procurement.

Voltage Reference Selection Notes

Select this part when a hermetically sealed, military-grade voltage reference is required. The SH suffix indicates the -55°C to +125°C operating range. Choose between SH and TH variants based on the required initial accuracy tolerance. Ensure the application benefits from the programmable output options to reduce inventory complexity.

Voltage Reference Part Context

The AD584 series provides flexible monolithic voltage references using laser wafer trimming. The SH/883B variant specifically meets military standards for reliability and environmental performance. It serves as a stable potential source for measurement and control systems where standard self-contained references may not provide sufficient precision.

Voltage Reference Replacement Considerations

The AD584TH/883B is a verified substitute offering higher initial accuracy (±0.14%) within the same temperature range and package.
