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 (75
) video
loads while providing 0.1dB of gain flatness to 30MHz.
Consumer video applications will also benefit from their 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/s of slew rate at a supply voltage of 5V. The
combination of high performance, low power, and excellent
video performance make these amplifiers well suited for use in
many digital consumer video appliances as well as many
general purpose high speed applications.

Absolute Maximum Ratings
The "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed. The device should
not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the
absolute maximum ratings. The "Recommended Operating Conditions" table defines the conditions for actual device operation.
Reliability Information
Note:
1. Package thermal resistance (
JA
), JDEC standard, multi-layer test boards, still air. Assumed power is concentrated in one channel
JA
will be lower,
if power is distributed in all channels.
