6 / 12 page AD546 REV. A –6– MINIMIZING INPUT CURRENT The AD546 is guaranteed to have less than 1 pA max input bias current at room temperature. Careful attention to how the am- plifier is used will reduce input currents in actual applications. The amplifier operating temperature should be kept as low as possible to minimize input current. Like other JFET input am- plifiers, the AD546’s input current is sensitive to chip tempera- ture, rising by a factor of 2.3 for every 10 °C rise. This is illustrated in Figure 24, a plot of AD546 input current versus ambient temperature. Figure 24. AD546 Input Bias Current vs Ambient Temperature On-chip power dissipation will raise chip operating temperature causing an increase in input bias current. Due to the AD546’s low quiescent supply current, chip temperature when the (unloaded) amplifier is operated with 15 V supplies, is less than 3 °C higher than ambient. The difference in input current is negligible. However, heavy output loads can cause a significant increase in chip temperature and a corresponding increase in input current. Maintaining a minimum load resistance of 10 k Ω is recom- mended. Input current versus additional power dissipation due to output drive current is plotted in Figure 25. Figure 25.
