Triple and Quad Voltage Feedback Amplifiers
Features at ±5V
Description
■ 0.1dB gain flatness to 30MHz
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.
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.
■ 0.07%/0.03˚ differential gain/phase error
■ 210MHz full power -3dB bandwidth at G = 2
■ 1,100V/µs slew rate
■ ±55mA output current (drives dual video load)
■ ±83mA output short circuit current
■ Output swings to within 1.3V of either rail
■ 3.6mA supply current per amplifier
■ Minimum stable gain of 3dB or 1.5V/V
■ FHP3350 - improved replacement for RC6333
■ FHP3450 - improved replacement for RC6334
■ Fully specified at +5V, and ±5V supplies
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
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.

General Description
OUT(RMS)
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.
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/µs 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.

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.

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 * (V + - V -) + (V + - V
) * I

Layout Considerations
General layout and supply bypassing play major roles in high
frequency performance. Fairchild has evaluation boards to use
as a guide for high frequency layout and as aid in device testing
and characterization. Follow the steps below as a basis for high
frequency layout:
• Include 6.8µF and 0.01µF ceramic capacitors
• Place the 6.8µF capacitor within 0.75 inches of the power pin
• Place the 0.01µF capacitor within 0.1 inches of the power pin
• Remove the ground plane under and around the part,
especially near the input and output pins to reduce parasitic
capacitance
• Minimize all trace lengths to reduce series inductances
Refer to the evaluation board layouts shown below for more
information.
