E | Page 12 of 1 6 Stacking the ADR520/ADR525/ADR530/ADR540/ADR550 for User-Definable Outputs Multiple ADR520/ADR525/ADR530/ADR540/ADR550 parts can be stacked to allow the user to obtain a desired higher voltage. Figure 22 shows three ADR550s configured to give 15 V. The bias resistor, RBIAS, is chosen using Equation 3; note that the same bias current flows through all the shunt references in series. Figure 23 shows three ADR550s stacked to give −15 V. RBIAS is calculated in the same manner as before. Parts of different voltages can also be added together. For example, an ADR525 and an ADR550 can be added together to give an output of +7.5 V or −7.5 V, as desired. Note, however, that the initial accuracy error is now the sum of the errors of all the stacked parts, as are the temperature coefficients and output voltage change vs. input current.

Figure 24 illustrates the implementation of this application using the ADR520/ADR525/ADR530/ADR540/ADR550. The output of the op amp, VOUT, is determined by the gain of the circuit, which is completely dependent on the resistors, R1 and R2. VOUT = VREF (1 + R2/R1) An additional capacitor, C1, in parallel with R2, can be added to filter out high frequency noise. The value of C1 is dependent on the value of R2.
