AD586 THEORY OF OPERATION The AD586 consists of a proprietary buried Zener diode refer- VIN ence, an amplifier to buffer the output, and several high stability 2 thin-film resistors, as shown in the block diagram in Figure 5.

By comparison, contribution by the op amp is negligible. Figure 7 AD586 shows the 0.1 Hz to 10 Hz noise of a typical AD586. The noise RZ1 RS measurement is made with a band-pass filter made of a 1-pole RZ2 A1 6 VOUT high-pass filter with a corner frequency at 0.1 Hz, and a 2-pole RF RT low-pass filter with a corner frequency at 12.6 Hz, to create a 5 TRIM filter with a 9.922 Hz bandwidth.

The AD586 is simple to use in virtually all precision reference applications. When power is applied to Pin 2 and Pin 4 is 1µF 5s grounded, Pin 6 provides a 5 V output. No external components are required; the degree of desired absolute accuracy is achieved simply by selecting the required device grade. The AD586 requires less than 3 mA quiescent current from an operating 1µF supply of 12 V or 15 V. An external fine trim may be desired to set the output level to exactly 5.000 V (calibrated to a main system reference). System calibration may also require a reference voltage that is slightly different from 5.000 V, for example, 5.12 V for binary applica- tciaonn so.f Ifnse et itthhee ro cuatpseu, tt hbey oasp tmiouncahl tarsi m30 c0i rmcuVi tw shitohw mni ninim Fiagl uerfefe 6c t 00529-006 Figure 7. 0.1 Hz to 10 Hz Noise on other device characteristics.

Two compo- nents normally associated with this are the time for the active circuits to settle, and the time for the thermal gradients on the chip to stabilize. Figure 9, Figure 10, and Figure 11 show the turn-on characteristics of the AD586. It shows the settling to be VOUT about 60 µs to 0.01%.

Capacitive Load Transient Response Test Circuit been characterized using a maximum deviation per degree Celsius, that is, ppm/°C. However, because of nonlinearities in temperature characteristics that originated in standard Zener references (such as “S” type characteristics), most manufacturers have begun to use a maximum limit error band approach to specify devices. This technique involves measuring the output at three or more different temperatures to specify an output volt- age error band. Rev. G | Page 9 of 16

AD586 5 V REFERENCE WITH MULTIPLYING 22V TO 46V CMOS DACs OR ADCs 2 The AD586 is ideal for applications with 10- and 12-bit VIN multiplying CMOS DACs. In the standard hookup, as shown VOUT 6 15V AD586 in Figure 20, the AD586 is paired with the AD7545 12-bit TRIM 5 10kΩ multiplying DAC and the AD711 high speed BiFET op amp.

STACKED PRECISION REFERENCES FOR The 0.1 µF capacitor is required only if the load has a significant MULTIPLE VOLTAGES capacitive component. If the load is purely resistive, improved high frequency supply rejection results can be obtained by Often, a design requires several reference voltages. Three removing the capacitor. AD586s can be stacked, as shown in Figure 22, to produce 5.000 V, 10.000 V, and 15.000 V outputs. This scheme can be extended to any number of AD586s, provided the maximum load current is not exceeded. This design provides the addi- tional advantage of improved line regulation on the 5.0 V output. Changes in V of 18 V to 50 V produce output changes IN that are below the noise level of the references. Rev. G | Page 11 of 16
