6 / 8 page AD746 –6– REV. B POWER SUPPLY BYPASSING The power supply connections to the AD746 must maintain a low impedance to ground over a bandwidth of 13 MHz or more. This is especially important when driving a significant resistive or capacitive load, since all current delivered to the load comes from the power supplies. Multiple high quality bypass capacitors are recommended for each power supply line in any critical application. A 0.1 µF ceramic and a 1 µF tantalum capacitor as shown in Figure 20 placed as close as possible to the amplifier (with short lead lengths to power supply common) will assure adequate high frequency bypassing, in most applications. A minimum bypass capacitance of 0.1 µF should be used for any application. If only one of the two amplifiers inside the AD746 is to be utilized, the unused amplifier should be connected as shown in Figure 21a. Note that the noninverting input should be grounded and that RL and CL are not required. Figure 19. THD Test Circuit Figure 22a. Unity Gain Inverter Figure 21a. Gain of 2 Follower Figure 21b.
