The AD587L has amaximum deviation from 10.000 V of ±8.5 mV between 0°C and +70°C, and the AD587U guarantees ±14 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 10 volt refer-ence can be upgraded instantly with the AD587.4.Output noise of the AD587 is very low, typically 4 µV p-p. A noise reduction pin is provided for additional noise filtering using an external capacitor.5.The AD587 is available in versions compliant with MIL-STD-883. Refer to the Analog Devices Military Products Databook or current AD587/883B data sheet for detailed specifications.PRODUCT DESCRIPTION The AD587 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 AD587 provides outstanding perfor-mance at low cost.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. The buried Zener approach to reference design pro-vides lower noise and drift than bandgap voltage references. The AD587 offers a noise reduction pin which can be used to further reduce the noise level generated by the buried Zener.The AD587 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 successiveapproximation 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 AD587J, K and L are specified for operation from 0°C to +70°C, and the AD587S, T and U are specified for –55°C to +125°C operation. All grades are available in 8-pin cerdip. The J and K versions are also available in an 8-pin Small Outline IC (SOIC) package for surface mount applications, while the J, K and L grades also come in an 8-pin plastic package.NOISE V OUTTRIMGNDNOTE:PINS 1,3 AND 7 ARE INTERNAL TEST POINTS.NO CONNECTIONS TO THESE POINTS.AD587–SPECIFICATIONS(T A = +25؇C, V IN = +15 V unless otherwise noted)Model AD587J/S AD587K/T AD587L/UMin Typ Max Min Typ Max Min Typ Max Units OUTPUT VOLTAGE9.99010.0109.99510.0059.99510.005VOUTPUT VOLTAGE DRIFT10°C to +70°C20105ppm/°C –55°C to +125°C20105GAIN ADJUSTMENT+3+3+3%–1–1–1LINE REGULATION113.5 V ≤ + V IN≤ 36 VT MIN to T MAX100100100±µV/VLOAD REGULATION1Sourcing 0 < I OUT < 10 mAT MIN to T MAX100100100±µV/mA Sourcing –10 < I OUT < 0 mA2T MIN to T MAX100100100QUIESCENT CURRENT242424mAPOWER DISSIPATION303030mWOUTPUT NOISE0.1 Hz to 10 Hz444µV p-pSpectral Density, 100 Hz100100100nV/√HzLONG-TERM STABILITY151515±ppm/1000 Hr.

C–4–THEORY OF OPERATIONThe AD587 consists of a proprietary buried Zener diode refer-ence, an amplifier to buffer the output and several high stability thin-film resistors as shown in the block diagram in Figure 1.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 under 5 ppm/°C.NOISE V OUTTRIM GNDNOTE:PINS 1,3 AND 7 ARE INTERNAL TEST POINTS.NO CONNECTIONS TO THESE POINTS.Figure 1.AD587 Functional Block Diagram A capacitor can be added at the NOISE REDUCTION pin (Pin 8) to form a low-pass filter with R S to reduce the noise contribu-tion of the Zener to the circuit.APPLYING THE AD587The 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 compo-nents 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 oper-ating supply of +15 V.Fine trimming may be desired to set the output level to exactly 10.000 V (calibrated to a main system reference). System cali-bration may also require a reference voltage that is slightly differ-ent from 10.000 V, for example, 10.24 V for binary applications.In either case, the optional trim circuit shown in Figure 2 can offset the output by as much as 300 mV, if desired, with mini-mal effect on other device characteristics.OUTPUTC Figure 2.Optional Fine Trim ConfigurationNOISE PERFORMANCE AND REDUCTIONThe 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 band-width is approximately 200 µV p-p. The dominant source of this noise is the buried Zener which contributes approximately 100 nV/√Hz . In comparison, the op amp’s contribution is negli-gible. Figure 3 shows the 0.1 Hz to 10 Hz noise of a typical AD587. The noise measurement is made with a bandpass 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.Figure 3.0.1 Hz to 10 Hz NoiseIf further noise reduction is desired, an external capacitor may be added between the NOISE REDUCTION pin and ground as shown in Figure 2. This capacitor, combined with the 4 k Ω R S and the Zener resistances, form a low-pass filter on the output of the Zener cell. A 1 µF capacitor will have a 3 dB point at 40 Hz, and it will reduce the high frequency (to 1 MHz) noise to about 160 µV p-p. Figure 4 shows the 1 MHz noise of a typi-cal AD587 both with and without a 1 µF capacitor.Figure 4.Effect of 1 µF Noise Reduction Capacitor on Broadband Noise TURN-ON TIMEUpon 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 5 shows the turn-on characteristics of theAD587. It shows the settling to be about 60 µs to 0.01%. Note the absence of any thermal tails when the horizontal scale is ex-panded to 1 ms/cm in Figure 5b.AD587REV. C–5–DYNAMIC PERFORMANCEThe output buffer amplifier is designed to provide the AD587 with static and dynamic load regulation superior to less com-plete references.Many A/D and D/A converters present transient current loads to the reference, and poor reference response can degrade the converter’s performance.Figure 6 displays the characteristics of the AD587 output ampli-fier driving a 0 mA to 10 mA load.Output turn-on time is modified when an external noise reduc-tion capacitor is used. When present, this capacitor acts as an additional load to the internal Zener diode’s current source, re-sulting 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% (see Figure 5c).a.Electrical Turn-Onb.Extended Time Scalec.Turn-On with 1 µF C N Figure 5.Turn-On CharacteristicsFigure 6a.Transient Load Test Circuit Figure rge-Scale Transient Response Figure 6c.Fine Scale Settling for Transient LoadOUTAD587REV. C–6–In some applications, a varying load may be both resistive and capacitive in nature, or the load may be connected to the AD587 by a long capacitive cable.Figure 7 displays the output amplifier characteristics driving a 1000 pF, 0 mA to 10 mA load.V OUTFigure 7a.Capacitive Load Transient /Response Test CircuitFigure 7b.Output Response with Capacitive Load LOAD REGULATIONThe AD587 has excellent load regulation characteristics. Figure 8 shows that varying the load several mA changes the output by only a few µV.Figure 8.Typical Load Regulation Characteristics TEMPERATURE PERFORMANCEThe AD587 is designed for precision reference applications where temperature performance is critical. Extensive tempera-ture 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 ref-erence voltage error over temperature. Historically, references have been characterized using a maximum deviation per degree Centrigrade; i.e., ppm/°C. However, because of nonlinearities in temperature characteristics which originated in standard Zener references (such as “S” type characteristics), most manufactur-ers 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 different temperatures to specify an out-put voltage error band.Figure 9 shows the typical output voltage drift for the AD587L and illustrates the test methodology. The box in Figure 9 is bounded on the sides by thc operating temperature extremes,and on the top and the bottom by the maximum and minimum output voltages measured over the operating temperature range.The slope of the diagonal drawn from the lower left to the upper right corner of the box determines the performance grade of the device.Figure 9.Typical AD587L Temperature DriftEach AD587J, K, L grade unit is tested at 0°C, +25°C and +70°C. Each AD587S, T, and U grade unit is tested at –55°C,+25°C and +125°C. This approach ensures that the variations of output voltage that occur as the temperature changes within the specified range will be contained within a box whose diago-nal has a slope equal to the maximum specified drift. The posi-tion of the box on the vertical scale will change from device to device as initial error and the shape of the curve vary. The maxi-mum height of the box for the appropriate temperature range and device grade is shown in Figure 10. Duplication of these results requires a combination of high accuracy and stable temperature control in a test system. Evaluation of the AD587will produce a curve similar to that in Figure 9, but output readings may vary depending on the test methods and equip-ment utilized.Figure 10.Maximum Output Change in mVAD587REV. C –7–NEGATIVE REFERENCE VOLTAGE FROM AN AD587The AD587 can be used to provide a precision –10.000 V output as shown in Figure 11. The V IN 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, R S , to a –15 V supply. The –10 V output is now taken from the ground pin (Pin 4) instead of V OUT . It is essential to arrange the output load and the sup-ply resistor R S so that the net current through the AD587 is be-tween 2.5 mA and 10.0 mA. The temperature characteristics and long-term stability of the device will be essentially the same as that of a unit used in the standard +10 V output configuration.1nF–15V–10VL <10mASFigure 11.AD587 as a Negative 10 V Reference USING THE AD587 WITH CONVERTERSThe AD587 is an ideal reference for a wide variety of 8-, 12-,14- and 16-bit A/D and D/A converters. Several representative examples follow.10 V REFERENCE WITH MULTIPLYING CMOS D/A OR A/D CONVERTERSThe AD587 is ideal for applications with 10- and 12-bit multi-plying CMOS D/A converters. In the standard hookup, as shown in Figure 12, the AD587 is paired with the AD754512-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 on the individual product data sheets.Figure 12.Low Power 12-Bit CMOS DAC ApplicationThe AD587 can also be used as a precision reference for mul-tiple DACs. Figure 13 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 DACsare on the same die and share a common reference and output op amps; the DAC outputs will exhibit similar gain TCs.Figure 13. AD587 as a 10 V Reference for a CMOS Dual DACPRECISION CURRENT SOURCEThe design of the AD587 allows it to be easily configured as a current source.

AUDIO ROUTINGThe flexiverter can operate in various routing modes, allowing you to pass audiobetween the available interfaces in many different ways. The LEDs in the "MODE"section indicate the involved interfaces.4.1.Modes and indication2All incoming data is also split (output) to FlexLink: AES50 Port A is split to Lane 1 (ch1-64), AES50 Port B is split to Lane 2 (ch65-128) and AUX is split to Lane 3 (ch129-192). The split is not indicated on the LEDs for clarity but is always active.FLX-AES504.2.Selecting the Route ModeLong-press the Mode button until the LEDs are blinking yellow.Current routing mode is shown by alternately yellow blinking LEDs, indicatingthe interfaces where the signal is passed between.Press the Mode button repeatedly to cycle between available modes, untilthe desired mode is shown.After four seconds without interaction, selection mode is terminated and thecurrent setting comes into effect.4.3.RemarksRouting between the selected interfaces is always bi-directional, meaning thataudio is passed between them both ways. A working bi-directional link shows⬤green for both interfaces. If the LED shows ⚪white, the correspondinginterface does only output data but no input on it has been detected. If the LEDshows ⬤ red, the interface is not connected, or the clock is invalid or missing.Channel-wise routing and splitting (crosspoint switch/matrix) between allchannels is possible when the flexiverter is connected to a multiverter. Routingis then done via the multiverter's web interface or via the command line.User's Manual5.
