As shown for the isolation buffer circuit capacitive load. Usually when an external op amp for capacitive load, will seriously affect the stability of the circuit, while its dy

namic performance will be severely degraded, and was able to better illustrated circuit driving a capacitive load, because the circuit uses a FET input type dielectric isolation wideband operational amplifier OPA606 composed isolation amplifier, and amplifying circuit with a carrying capacity tends to idealize. The reason why this circuit has such a good load capacity, due to the OPA606 has its own characteristics and the external circuit of the RC compensation network. The figure shows the resistance of the access circuit is 10k resistor R1 and the compensation capacitor C1 (with a capacity of 20pF).
