7.1.1 Driving a Capacitive Load

The THS403x devices are internally compensated to maximize bandwidth and slew-rate performance. Take additional precautions when driving capacitive loads with a high-performance amplifier to maintain stability. As a result of the internal compensation, significant capacitive loading directly on the output node decreases the device phase margin, and potentially leads to high-frequency ringing or oscillations. Therefore, for capacitive loads greater than 10 pF, place an isolation resistor in series with the output of the amplifier. Figure 7-1 shows this configuration. For most applications, a minimum resistance of 20 Ω is recommended. In 75‑Ω transmission systems, setting the series resistor value to 75 Ω is a beneficial choice because this value isolates any capacitance loading and provides source impedance matching.
