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.

FHP3350, FHP3450 Triple and Quad Voltage Feedback Amplifiers
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 (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.
Where Is is the supply current, Vs+ is the positive supply pin voltage, Vs- is the negative supply pin voltage, Vo(RMS) is the RMS output voltage and IOUT(RMS) is the RMS output current delivered to the load. Follow the maximum power derating curves shown in Figure 32 below to ensure proper operation.

Figure 32. Maximum Power Derating 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.
Driving Capacitive Loads
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 bandwidth with less than 1dB of peaking. For maximum flatness, use a larger Rs.

Figure 31. Typical Topology for driving capacitive loads Power Dissipation
The maximum internal power dissipation allowed is directly related to the maximum junction temperature. If the maximum junction temperature exceeds 150C 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 (+150C) 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 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 6.8F and 0.01F ceramic capacitors * Place the 6.8F capacitor within 0.75 inches of the power pin * Place the 0.01F 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.
