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 and 30 volts. Laser Wafer Trimming (LWT) is used to adjust the pin-pro- grammable 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 µA. In the “on” state the total supply current is typically 750 µA 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 refer- ence. The device is also ideal for all types of A/D converters of up to 14-bit accuracy, either successive approximation or inte- grating 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 eight-terminal TO-99 metal can; the AD584 J and K are also available in an 8-pin plastic DIP. *Protected by U.S. Patent No. 3,887,863; RE 30,586 One Technology Way, P.O. Box 9106, Norwood, MA 02062-9106, U.S.A. Tel: 617/329-4700 Fax: 617/326-8703 PRODUCT HIGHLIGHTS 1. The flexibility of the AD584 eliminates the need to design- in and inventory several different voltage references. Fur- thermore one AD584 can serve as several references simultaneously when buffered properly. 2. Laser trimming of both initial accuracy and temperature co- efficient results in very low errors over temperature without the use of external components. The AD584LH has a maxi- mum deviation from 10.000 volts of ±7.25 mV from 0°C to +70 °C. 3. The AD584 can be operated in a two-terminal “Zener” mode at 5 volts output and above. By connecting the input and the output, the AD584 can be used in this “Zener” con- figuration 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 tol- erated 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. |
