... GENERAL DESCRIPTION (continued from Page 1) The AD822 drives up to 350 pF of direct capacitive load as a follower and provides a minimum output current of 15 mA. This allows the amplifier to handle a wide range of load conditions. Its combination of ac and dc performance, plus the outstanding load drive capability, results in an exceptionally versatile amplifier for the single-supply user ...

... The AD822 can be configured as a single-supply instrumenta- tion amplifier that is able to operate from single supplies down dual supplies up to ±15 V. Using only one AD822 rather than three separate op amps, this circuit is cost and power efficient. The AD822 FET inputs’ bias currents minimize offset errors caused by high unbalanced source impedances ...
