PRODUCT DESCRIPTION
The AD586 represents a major advance in the state-of-the-art in
monolithic voltage references. Using a proprietary ion-implanted
buried Zener diode and laser wafer trimming of high stability
thin-film resistors, the AD586 provides outstanding perfor-
mance at low cost.
The AD586 offers much higher performance than most other
5 V references. Because the AD586 uses an industry standard
pinout, many systems can be upgraded instantly with the
AD586. The buried Zener approach to reference design pro-
vides lower noise and drift than bandgap voltage references. The
AD586 offers a noise reduction pin which can be used to further
reduce the noise level generated by the buried Zener.
The AD586 is recommended for use as a reference for 8-, 10-,
12-, 14- or 16-bit D/A converters which require an external
precision reference. The device is also ideal for successive
approximation or integrating A/D converters with up to 14 bits
of accuracy and, in general, can offer better performance than
the standard on-chip references.
The AD586J, K, L and M are specified for operation from 0 C
to +70 C, the AD586A and B are specified for –40 C to +85 C
operation, and the AD586S and T are specified for –55 C to
+125 C operation. The AD586J, K, L and M are available in an
8-pin plastic DIP. The AD586J, K, L, A and B are available in
an 8-pin plastic surface mount small outline (SO) package. The
AD586J, K, L, S and T are available in an 8-pin cerdip package.
