... This is accomplished by connecting a capacitor between Pins 5 and 8. Figure 28, a simplified schematic of the AD744, shows where this capacitor is connected. This feature is useful because it allows the AD744 to be used as a unity gain voltage follower. It also enables the amplifier to drive capacitive loads up to 2000 pF and greater. ...
