GENERAL DESCRIPTION

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. Other output voltages, above, below or between the four standard outputs, are available by the addition of external resistors. Input voltage may vary between 4.5 V and 30 V.

Laser Wafer Trimming (LWT) is used to adjust the pinprogrammable output levels and temperature coefficients, resulting in the most flexible high precision voltage reference available in monolithic form.

In addition to the programmable output voltages, the AD584 offers a unique strobe terminal which permits the device to be turned on or off. When the AD584 is used as a power supply reference, the supply can be switched off with a single, low-power signal. In the “off” state the current drain by the AD584 is reduced to about 100 A. In the “on” state the total supply current is typically 750 A including the output buffer amplifier.

The AD584 is recommended for use as a reference for 8-, 10-, or 12-bit D/A converters which require an external precision reference. The device is also ideal for all types of A/D converters of up to 14-bit accuracy, either successive approximation or integrating designs, and in general can offer better performance than that provided by standard self-contained references.

The AD584J, K, and L are specified for operation from 0°C to 70°C; the AD584S and T are specified for the –55°C to +125°C range. All grades are packaged in a hermetically sealed eightterminal TO-99 metal can; the AD584 J and K are also available in an 8-lead plastic DIP.

PRODUCT HIGHLIGHTS

1.The flexibility of the AD584 eliminates the need to design-in and inventory several different voltage references. Further more one AD584 can serve as several references simultaneously when buffered properly.

2.Laser trimming of both initial accuracy and temperature coefficient results in very low errors over temperature without the

use of external components. The AD584LH has a maximum deviation from 10.000 V of ±7.25 mV from 0°C to 70°C.

3.The AD584 can be operated in a two-terminal “Zener” mode at 5 V output and above. By connecting the input and the output, the AD584 can be used in this “Zener” configuration as a negative reference.

4.The output of the AD584 is configured to sink or source currents. This means that small reverse currents can be tolerated in circuits using the AD584 without damage to the reference and without disturbing the output voltage (10 V, 7.5 V, and 5 V outputs).

5.The AD584 is available in versions compliant with MIL-STD- 883. Refer to the Analog Devices Military Products Databook or current AD584/883B data sheet for detailed specifications.

CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AD584 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.
