Using a proprietary ionimplanted buried Zener diode and laser wafer trimming of high stability thin-film resistors, the AD587 provides outstanding performance at low cost. 1. The AD587 offers much higher performance than most other 10 V references. Because the AD587 uses an industry-standard pinout, many systems can be upgraded instantly with the AD587. 2. The buried Zener approach to reference design provides lower noise and drift than band gap voltage references. The AD587 offers a noise-reduction pin that can be used to further reduce the noise level generated by the buried Zener. 4. The AD587 is recommended for use as a reference for 8-bit, 10-bit, 12-bit, 14-bit, or 16-bit DACs that require an external precision reference. The device is also ideal for successive approximation or integrating ADCs with up to 14 bits of accuracy. In general, it offers better performance than standard on-chip references. 3. 5. Laser trimming of both initial accuracy and temperature coefficients. This laser trimming results in very low errors over temperature without the use of external components. The AD587U guarantees ±14 mV maximum total error between −55°C and +125°C. Optional fine trim connection. This connection is designed for applications requiring higher precision. Instant upgrade of any system using an industry-standard pinout 10 V reference. Very low output noise. AD587 output noise is typically 4 μV p-p. A noise-reduction pin is provided for additional noise filtering using an external capacitor. MIL-STD-883-compliant versions available. Refer to the Analog Devices Military/Aerospace Reference Manual for detailed specifications. The AD587J and AD587K are specified for operation from 0°C to 70°C, and the AD587U is specified for operation from −55°C to +125°C. The AD587JQ and AD587UQ models are available in 8-lead CERDIP. Other models are available in an 8-lead SOIC package for surface-mount applications, or in an 8-lead PDIP. Rev. H Information furnished by Analog Devices is believed to be accurate and reliable.

H | Page 5 of 12 AD587 THEORY OF OPERATION The AD587 consists of a proprietary buried Zener diode reference, an amplifier to buffer the output, and several high stability thin-film resistors, as shown in Figure 3. This design results in a high precision monolithic 10 V output reference with initial offset of 5 mV or less. The temperature-compensation circuitry provides the device with a temperature coefficient of less than 5 ppm/°C. +VIN NOISE REDUCTION 2 8 RS 6 VOUT A1 NOISE PERFORMANCE AND REDUCTION Noise generated by the AD587 is typically less than 4 μV p-p over the 0.1 Hz to 10 Hz band. Noise in a 1 MHz bandwidth is approximately 200 μV p-p. The dominant source of this noise is the buried Zener, contributing approximately 100 nV/√Hz. By comparison, the contribution of the op amp is negligible. Figure 5 shows the 0.1 Hz to 10 Hz noise of a typical AD587. The noise measurement is made with a band-pass filter made of a 1-pole high-pass filter with a corner frequency at 0.1 Hz and a 2-pole low-pass filter with a corner frequency at 12.6 Hz to create a filter with a 9.922 Hz bandwidth.

Functional Block Diagram 00530-005 A capacitor can be added at the NOISE REDUCTION pin (Pin 8) to form a low-pass filter with RS to reduce the noise contribution of the Zener to the circuit. Figure 5. 0.1 Hz to 10 Hz Noise APPLYING THE AD587 The AD587 is simple to use in virtually all precision reference applications. When power is applied to Pin 2 and Pin 4 is grounded, Pin 6 provides a 10 V output. No external components are required; the degree of desired absolute accuracy is achieved simply by selecting the required device grade. The AD587 requires less than 4 mA quiescent current from an operating supply of 15 V. If further noise reduction is desired, an external capacitor can be added between the NOISE REDUCTION pin and ground, as shown in Figure 4. This capacitor, combined with the 4 kΩ RS and the Zener resistances, forms a low-pass filter on the output of the Zener cell. A 1 μF capacitor has a 3 dB point at 40 Hz and reduces the high frequency (up to 1 MHz) noise to about 160 μV p-p. Figure 6 shows the 1 MHz noise of a typical AD587, both with and without a 1 μF capacitor. Fine trimming may be desired to set the output level to exactly 10.000 V (calibrated to a main system reference). System calibration may also require a reference voltage that is slightly different from 10.000 V, for example, 10.24 V for binary applications. In either case, the optional fine-trimming circuit shown in Figure 4 can offset the output by as much as 300 mV with minimal effect on other device characteristics. 200µV CN – 1µF +VIN CN 1µF NO CN 50µs 100 90 10 0% 2 VOUT 6 NOISE 8 REDUCTION OUTPUT Figure 6.

H | Page 6 of 12 AD587 TURN-ON TIME 10V Upon application of power (cold start), the time required for the output voltage to reach its final value within a specified error band is defined as the turn-on settling time. Two components 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 7, Figure 8, and Figure 9 show the turnon characteristics of the AD587. These figures show the settling to be about 60 μs to 0.01%. Note the absence of any thermal tails when the horizontal scale is expanded to 1 ms/cm in Figure 8. 1mV 10V +VIN 100 90 VOUT 10 0% 00530-009 Output turn-on time is modified when an external noise reduction capacitor is used. When present, this capacitor acts as an additional load to the current source of the internal Zener diode, resulting in a somewhat longer turn-on time. In the case of a 1 μF capacitor, the initial turn-on time is approximately 400 ms to 0.01%, as shown in Figure 9. Figure 9. Turn-On with 1 μF CN DYNAMIC PERFORMANCE The output buffer amplifier is designed to provide the AD587 with static and dynamic load regulation that is superior to less complete references. Many ADCs and DACs present transient current loads to the reference, and poor reference response can degrade the converter’s performance. +VIN 100 90 Figure 11 and Figure 12 display the characteristics of the AD587 output amplifier driving a 0 mA to 10 mA load.

Capacitive Load Transient/Response Test Circuit 10V 200mV The AD587 is designed for precision reference applications where temperature performance is critical. Extensive temperature testing ensures that the device’s high level of performance is maintained over the operating temperature range. Some confusion exists in the area of defining and specifying reference voltage error over temperature. Historically, references have been characterized using a maximum deviation per degree Celsius, such as 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 the measurement of the output at three or more temperatures to specify an output voltage error band. 1µs CL = 0 100 90 10 0% VL 00530-014 CL = 1000pF Figure 14. Output Response with Capacitive Load LOAD REGULATION The AD587 has excellent load regulation characteristics. Figure 15 shows that varying the load several milliamperes changes the output by only a few microvolts. Rev. H | Page 8 of 12 AD587 Each AD587J and AD587K grade unit is tested at 0°C, 25°C, and 70°C. Each AD587U grade unit is tested at −55°C, +25°C, and +125°C. This approach ensures that the variations of the output voltage that occur as the temperature changes within the specified range are contained within a box whose diagonal has a slope equal to the maximum specified drift. The position of the box on the vertical scale changes from device to device as initial error and the shape of the curve vary. The maximum height of the box for the appropriate temperature range and device grade is shown in Figure 16. Duplication of these results requires a combination of high accuracy and stable temperature control in a test system.

The +VIN pin is tied to at least a +3.5 V supply, the output pin is grounded, and the AD587 ground pin is connected through a resistor (RS) to a −15 V supply. The −10 V output is taken from the ground pin (Pin 4) instead of VOUT. It is essential to arrange the output load and the supply resistor (RS) so that the net current through the AD587 is between 2.5 mA and 10.0 mA (RS should be kept below 1 kΩ). The temperature characteristics and long-term stability of the device is essentially the same as that of a unit used in the standard 10 V output configuration. 00530-017 DEVICE GRADE NEGATIVE REFERENCE VOLTAGE FROM AN AD587 Figure 17.

H | Page 9 of 12 AD587 APPLICATIONS INFORMATION +VIN USING THE AD587 WITH CONVERTERS The AD587 is an ideal reference for a variety of 8-bit, 12-bit, 14-bit, and 16-bit ADCs and DACs. Several examples follow. 2 +VIN VOUT 6 10 V Reference with Multiplying CMOS DACs or ADCs AD587 The AD587 is ideal for applications with 10-bit and 12-bit multiplying CMOS DACs. In the standard hookup, shown in Figure 18, the AD587 is paired with the AD7545 12-bit multiplying DAC and the AD711 high speed BiFET op amp. The amplifier DAC configuration produces a unipolar 0 V to −10 V output range. Bipolar output applications and other operating details can be found in the individual product data sheets. 4 Figure 20. Precision Current Source Precision High Current Supply For higher currents, the AD587 can easily be connected to a power PNP or power Darlington PNP device. The circuits in Figure 21 and Figure 22 can deliver up to 4 A to the load. The 0.1 μF capacitor is required only if the load has a significant capacitive component. If the load is purely resistive, improved high frequency supply rejection results can be obtained by removing the capacitor. +15V +15V R2 0.1µF C1 +15V 33pF 0.1µF +VIN TRIM RFB OUT1 VREF AD711 AD7545 10kΩ AGND +VIN 0.1µF DGND GND VOUT 0V TO –10V DB11 TO DB0 –15V 220Ω 2N6285 Figure 18.

Figure 19 shows the AD587, the AD7628 dual DAC, and the AD712 dual op amp hooked up for single-supply operation to produce 0 V to −10 V outputs. Because both DACs are on the same die and share a common reference and output op amps, the DAC outputs will exhibit similar gain temperature coefficients (TCs). 0.1µF 2 +VIN VOUT 6 AD587 +15V +15V VOUT OUT A Figure 21.
