... MAXIMUM POWER DISSIPATION The maximum power that can be safely dissipated by the ADA4858-3 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. Temporarily − ...

... The ADA4858-3 can be used in applications that require both ac- and dc-coupled inputs and outputs. The output stage on the ADA4858-3 is capable of driving 2 V p-p video signals into two doubly terminated video loads (150 Ω each single 5 V supply. The input range of the ADA4858-3 includes ground, and the output range is limited by the output headroom set by the voltage drop across the two diodes from each rail, which occurs 1 ...

... Figure 39. Inverting Gain Configuration DC-COUPLED VIDEO SIGNAL The ADA4858-3 does not have a rail-to-rail output stage. The output can be within the rails. Having a charge pump on board that can provide − supply and − +3.3 V supply makes this part excellent for video applications. In dc-coupled applications, the black color has voltage reference ...

... These applications require a signal dc clamp on the output of the video driver to restore the dc level reference. The ADA4858-3 has a charge pump that allows the output to swing negative; twice the sync tip (−600 mV configuration. Figure 44 shows the ADA4858 difference amplifier configuration ...

... ADA4858-3 PD (POWER-DOWN) PIN The ADA4858-3 is equipped with a PD (power-down) pin for all three amplifiers. This allows the user to reduce the quiescent supply current when an amplifier is not active. The power- down threshold levels are derived from ground level. The amplifiers are powered down when the voltage applied to the PD pin is greater than a certain voltage from ground ...
