... AD8517/AD8527 TIME – 1s/Div TIME – 200 s/Div THEORY OF OPERATION The AD85x7 is a rail-to-rail operational amplifier that can operate at supply voltages as low as 1.8 V. This family is fabricated using Analog Devices’ high-speed complementary bipolar process, also called XFCB. The process trench isolates each transistor to minimize parasitic capacitance thereby allowing high-speed performance ...

... AD8517/AD8527 DRIVING CAPACITIVE LOAD Gain vs. Capacitive Load Most amplifiers have difficulty driving capacitance due to degradation of phase caused by additional phase lag from the capacitive load. Higher capacitance at the output can increase the amount of over- shoot and ringing in the amplifier’s step response and could even affect the stability of the device ...
