7 / 9 page REF102 ® 7 FIGURE 4. REF102 Optional Output Voltage Fine Adjust. Higher resolution, reduced range (typically ±25mV). APPLICATIONS INFORMATION High accuracy, extremely low drift, outstanding stability, and low cost make the REF102 an ideal choice for all instrumentation and system reference applications. Figures 6 through 14 show a variety of useful application circuits. FIGURE 6. –10V Reference Using a) Resistor or b) OPA27. See AB-004 for more detail 1.4mA < (5V –I L ) < 5.4mA R S OPTIONAL NOISE REDUCTION The high-frequency noise of the REF102 is dominated by the zener diode noise. This noise can be greatly reduced by connecting a capacitor between the Noise Reduction pin and ground. The capacitor forms a low pass filter with R6 (refer to the figure on the first page of the data sheet) and attenu- ates the high-frequency noise generated by the zener. Figure 5 shows the effect of a 1 µF noise reduction capacitor on the high frequency noise of the REF102. R6 is typically 7kΩ so the filter has a –3dB frequency of about 22Hz. The result is a reduction in noise from about 800 µVp-p to under 200µ Vp-p. If further noise reduction is required, use the circuit in Figure 14. FIGURE 5.
