Triple and Quad Voltage Feedback Amplifiers
Features
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 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.
■ 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 suppliesꢀ
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.
Applications
■ Video driver
■ RGB driver
■ ADC buffer
■ S-video amp

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.

Where Is is the supply current, Vs+ is the positive supply pin volt-
age, Vs- is the negative supply pin voltage, Vo(RMS) is the RMS out-
put voltage and IOUT(RMS) is the RMS output current delivered to the
load. Follow the maximum power derating curves shown in Fig-
ure 32 below to ensure proper operation.
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.

OverdriveꢀRecovery
Driving Capacitive Loads
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.
The Frequency Response vs. CL plot on page 8, illustrates the
response of the FHP3350 Family. A small series resistance (Rs)
at the output of the amplifier, illustrated in Figure 1, will improve
stability and settling performance. Rs values in the Frequency
Response vs. CL plot were chosen to achieve maximum band-
width with less than 1dB of peaking. For maximum flatness, use a
larger Rs.

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 = Is * (Vs+ - Vs-) + (Vs+ - Vo(RMS)) * IOUT(RMS)

Layout Considerations
General layout and supply bypassing play major roles in high fre-
quency 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 fre-
quency 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 below for more information.
