2 / 4 page 2 AN1509.0 November 6, 2009 User-selectable Options (Figures 3 and 4) Component pads are included to enable a variety of user-selectable circuits to be added to the amplifier VREF, inputs, outputs, and the amplifier feedback loops. The Inputs (Figure 3) have additional resistor and capacitor, and jumper placements for loading and/or measurement of frequency sensitive parameters. The outputs (Figure 4) have additional resistor and capacitor placements for loading. NOTE: Operational amplifiers are sensitive to output capacitance and may oscillate. In the event of oscillation, reduce output capacitance by using shorter cables, or add a resistor in series with the output. FIGURE 3. INPUT STAGE (1/2) FIGURE 4.
