... MAXIMUM POWER DISSIPATION The maximum power that can be safely dissipated by the AD8042 is limited by the associated rise in junction temperature. The maximum safe junction temperature for plastic encapsulated devices is determined by the glass transition temperature of the plastic, approximately 150°C. Exceeding this limit temporarily can cause a shift in parametric performance due to a change in the stresses exerted on the die by the package ...

... ESD devices do begin to conduct if the input voltages exceed the rails by greater than 0.5 V. DRIVING CAPACITIVE LOADS The capacitive load drive of the AD8042 can be increased by adding a low valued resistor in series with the load. Figure 36 shows the effects of a series resistor on capacitive drive for varying voltage gains ...

... Single-Supply Composite Video Line Driver The two op amps of an AD8042 can be configured as a single- supply dual line driver for composite video. The wide signal swing of the AD8042 enables this function to be performed without using any type of clamping or dc restore circuit, which can cause signal distortion ...
