GENERAL DESCRIPTION
The AD584 is an 8-terminal precision voltage reference offering The AD584J and AD584K are specified for operation from 0°C pin programmable selection of four popular output voltages: to +70°C, and the AD584S and AD584T are specified for the 10.000 V, 7.500 V, 5.000 V and 2.500 V. Other output voltages, −55°C to +125°C range. Al grades are packaged in a hermetical y above, below, or between the four standard outputs, are available by sealed, eight-terminal TO-99 metal can, and the AD584J and the addition of external resistors. The input voltage can vary AD584K are also available in an 8-lead PDIP. between 4.5 V and 30 V.
PRODUCT HIGHLIGHTS
Laser wafer trimming (LWT) is used to adjust the pin 1. The flexibility of the AD584 eliminates the need to design- programmable output levels and temperature coefficients, in and inventory several different voltage references. resulting in the most flexible high precision voltage reference Furthermore, one AD584 can serve as several references available in monolithic form. simultaneously when buffered properly. In addition to the programmable output voltages, the AD584 2. Laser trimming of both initial accuracy and temperature offers a unique strobe terminal that permits the device to be coefficient results in very low errors overtemperature turned on or off. When the AD584 is used as a power supply without the use of external components. reference, the supply can be switched off with a single, low power 3. The AD584 can be operated in a 2-terminal Zener mode at signal. In the off state, the current drained by the AD584 is reduced a 5 V output and above. By connecting the input and the to approximately 100 µA. In the on state, the total supply current is output, the AD584 can be used in this Zener configuration typical y 750 µA, including the output buffer amplifier. as a negative reference. The AD584 is recommended for use as a reference for 8-, 10-, 4. The output of the AD584 is configured to sink or source or 12-bit digital-to-analog converters (DACs) that require an currents. This means that small reverse currents can be external precision reference. In addition, the device is ideal for tolerated in circuits using the AD584 without damage to analog-to-digital converters (ADCs) of up to 14-bit accuracy, the reference and without disturbing the output voltage either successive approximation or integrating designs, and in (10 V, 7.5 V, and 5 V outputs). general, it can offer better performance than that provided by 5. The AD584 is available in versions compliant with MIL-STD- standard self-contained references. 883. Refer to the Analog Devices current AD584/883B data sheet for detailed specifications.
