Applications Information
General Description
The FHP3350 and FHP3450 are low-cost, high-performance,
voltage feedback amplifiers designed for video applications.
These triple and quad amplifiers consume only 3.6mA of supply
current per channel and are capable of driving dual (75Ω) video
loads while providing 0.1dB of gain flatness to 30MHz. Consum-
er video applications also benefit from the low 0.07% differential
gain and 0.03° differential phase errors. The FHP3350 offers
three outputs that can be put into a high-impedance disable state
to allow for video multiplexing or minimize power consumption.
These amplifiers are designed to operate from 5V (±2.5V) to 12V
(±6V) supplies. The outputs swing to within 1.3V of either supply
rail to accommodate video signals on a single 5V supply.
The FHP3350 and FHP3450 are designed on a complementary
bipolar process. They provide 210MHz of full-power bandwidth
and 1,100V/μs of slew rate at a supply voltage of ±5V. The combi-
nation of high performance, low power, and excellent video per-
formance make these amplifiers well suited for use in many digi-
tal consumer video appliances as well as many general-purpose,
high-speed applications.

Power Dissipation
The maximum internal power dissipation allowed is directly
related to the maximum junction temperature. If the maximum
junction temperature exceeds 150°C for an extended time,
device failure may occur. The FHP3350 and FHP3450 are short
circuit protected. However, this may not guarantee that the
maximum junction temperature (+150°C) is not exceeded under
all conditions. RMS Power Dissipation can be calculated using
the following equation:
Power Dissipation = I

Overdrive Recovery
For an amplifier, an overdrive condition occurs when the output
and/or input ranges are exceeded. The recovery time varies
based on whether the input or output is overdriven and by how
much the ranges are exceeded. The FHP3350/3450 will typically
recover in less than 50ns from an overdrive condition. Figure 33
shows the FHP3350 in an overdriven condition.
