Figure 27. Circuit for Driving a Large Capacitance Load
The circuit in Figure 27 employs a 100
isolation resistor
which enables the amplifier to drive capacitance loads exceeding
500 pF; the resistor effectively isolates the high frequency feed-
back from the load and stabilizes the circuit. Low frequency
feedback is returned to the amplifier summing junction via the
low-pass filter formed by the 100
series resistor and the load
capacitance, C

Figure 25. Settling Time Test Circuit
The upper trace of the oscilloscope photograph of Figure 26
shows the settling characteristic of the AD544. The lower trace
represents the input to Figure 27. The AD544 has been designed
for fast settling to 0.01%, however, feedback components, cir-
cuit layout and circuit design must be carefully considered to
obtain optimum settling time.
