The AD586 represents a major advance in state-of-the-art 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 performance 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 provides lower noise and drift than band gap voltage references. The AD586 offers a noise reduction pin that can be used to further reduce the noise level generated by the buried Zener.

The AD586 is recommended for use as a reference for or 16-bit DACs that require an external precision reference. The device is also ideal for successive approximation or integrating ADCs with to 14 bits of accuracy and, in general, can offer better performance than the standard on-chip references.

The AD586K, AD586L, and AD586M are specified for operation from to 70°C; the AD586A and AD586B are specified for to +85°C operation; and the AD586S and AD586T are specified for to +125°C operation.

The AD586K, AD586L, and AD586M are available an 8-lead PDIP; the AD586L, AD586A, and AD586B are available an 8-lead SOIC package; and the AD586L, AD586S, and AD586T are available an 8-lead CERDIP package.

1. Laser trimming of both initial accuracy and temperature coefficients results in very low errors over temperature without the use of external components. The AD586M has a maximum deviation from ±2.45 mV between 0°C and 70°C, and the AD586T guarantees ±7.5 mV maximum total error between -55°C and +125°C.

2. For applications requiring higher precision, an optional fine-trim connection is provided.
3. Any system using an industry-standard pinout reference can be upgraded instantly with the AD586.

4. Output noise of the AD586 is very low, typically 4 µV p-p. A noise reduction pin is provided for additional noise filtering using an external capacitor.

5. The AD586 is available in versions compliant with MIL-STD-883. Refer to the Analog Devices Military Products Databook or the current AD586/883B data sheet for detailed specifications.
