The AD584 is an eight-terminal precision voltage reference offering pin-programmable selection of four popular output voltages: 10.000 V, 7.500 V, 5.000 V, and 2.500 V. It features high accuracy, no external components required, trimmed temperature coefficient, and stable output.
The AD584 is an eight‑terminal precision voltage reference that provides four programmable output voltages (10.000 V, 7.500 V, 5.000 V, 2.500 V). It includes a unique strobe terminal for turning the output on or off and can operate in a two‑terminal Zener mode for negative references.
The device is available in hermetically sealed TO‑99 metal cans and plastic DIP packages, with grades covering temperature ranges from –55 °C to +125 °C. It offers low quiescent current, high output current capability, and options for MIL‑STD‑883 compliance.
| Programmable Output Voltages | 10.000 V, 7.500 V, 5.000 V, 2.500 V |
|---|---|
| Output Voltage Tolerance (10 V) | +30 mV / –10 mV |
| Maximum Output Current | 10 mA |
| Temperature Coefficient (L grade) | 5 ppm/°C (0 °C – 70 °C) |
The AD584 can be programmed to output 10.000 V, 7.500 V, 5.000 V, or 2.500 V.
Pulling the strobe pin low to less than 200 mV disables the output, reducing the device’s current drain to about 100 µA.
The AD584L grade offers a temperature coefficient of 5 ppm/°C over the 0 °C to 70 °C range.
