DRIVING CAPACITIVE LOADS

As noted previously, capacitive loads should be isolated from the amplifier output with small valued resistors.

This is particularly the case when the load has a resistive component that is 500Ω or higher. A typical ADC has

capacitive components of around 10 pF and the resistive component could be 1000Ω or higher. If driving a

transmission line, such as 50Ω coaxial or 100Ω twisted pair, using matching resistors will be sufficient to isolate

any subsequent capacitance.

BALANCED CABLE DRIVER

With up to 15 V

differential output voltage swing and 80 mA of linear drive current the LMH6552 makes an

excellent cable driver as shown in Figure 54. The LMH6552 is also suitable for driving differential cables from a

single ended source.
