Using a proprietary ion-implanted NOTES buried Zener diode and laser wafer trimming of high stability 1. PINS 1, 3, AND 7 ARE INTERNAL TEST POINTS. MAKE NO CONNECTIONS TO THESE POINTS. thin-film resistors, the AD586 provides outstanding perform- Figure 1. ance at low cost. The AD586 offers much higher performance than most other PRODUCT HIGHLIGHTS 5 V references. Because the AD586 uses an industry-standard 1. Laser trimming of both initial accuracy and temperature pinout, many systems can be upgraded instantly with the coefficients results in very low errors over temperature AD586. without the use of external components. The AD586M has a maximum deviation from 5.000 V of 2.45 mV between The buried Zener approach to reference design provides lower 0C and 70C, and the AD586T guarantees 7.5 mV noise and drift than band gap voltage references. The AD586 maximum total error between 55C and +125C. offers a noise reduction pin that can be used to further reduce the noise level generated by the buried Zener. 2. For applications requiring higher precision, an optional fine-trim connection is provided. The AD586 is recommended for use as a reference for 8-, 10-, 12-, 14-, or 16-bit DACs that require an external precision 3. Any system using an industry-standard pinout reference reference. The device is also ideal for successive approximation can be upgraded instantly with the AD586. or integrating ADCs with up to 14 bits of accuracy and, in general, can offer better performance than the standard on-chip 4. Output noise of the AD586 is very low, typically 4 V p-p. references. A noise reduction pin is provided for additional noise filtering using an external capacitor. The AD586J, AD586K, AD586L, and AD586M are specified for operation from 0C to 70C the AD586A and AD586B are 5. The AD586 is available in versions compliant with specified for 40C to +85C operation and the AD586S and MIL-STD-883. Refer to the Analog Devices Military AD586T are specified for 55C to +125C operation. Products Databook or the current AD586/883B data sheet for detailed specifications. Rev.
