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.

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. 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.

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. 2 1.5 Vs = ±2.5V G = +5 Output Amplitude (V) Rs CL RL 1 0.5 0 -0.5 -1 -1.5 -2 0 0.1 02 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1 Input Rf Rg 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 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) Time (µs) Figure 33. Overdrive Recovery FHP3350, FHP3450 Rev. 1A 13 www.fairchildsemi.com FHP3350, FHP3450 Triple and Quad Voltage Feedback Amplifiers 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. Evaluation Board Information The following evaluation boards are available to aid in the testing and layout of thes devices: Evaluation Board # KEB019 KEB020 KEB012 KEB018 Products FHP3350IM14X FHP3350IMTC14X FHP3450IMTC14X FHP3450IM14X Figure 35.

Dimension "E1" does not include interlead flash or protusion. Interlead flash or protusion shall not exceed 0.25 per side. Dimension "b" does not include dambar protusion. Allowable dambar protusion shall be 0.08mm total in excess of the "b" dimension at maximum material condition. Dambar connot be located on the lower radius of the foot. Minimum space between protusion and adjacent lead is 0.07mm for 0.5mm pitch packages. Terminal numbers are shown for reference only. Datums – A – and – B – to be determined at datum plane – H – . Dimensions "D" and "E1" to be determined at datum plane – H – . This dimensions applies only to variations with an even number of leads per side. For variation with an odd number of leads per side, the "center" lead must be coincident with the package centerline, Datum A. Cross sections A – A to be determined at 0.10 to 0.25mm from the leadtip. 6 7 8 9 10 FHP3350, FHP3450 Rev. 1A 17 www.fairchildsemi.com FHP3350, FHP3450 Triple and Quad Voltage Feedback Amplifiers 14-Lead Small Outline Package (SOIC) SOIC-14 D e ZD C L 7° SYMBOL A1 B C D E e H h L A ZD A2 L MIN MAX .0040 .0098 .014 .018 .0075 .0098 .337 .344 .150 .157 .050 BSC .2284 .2440 .0099 .0196 .016 .050 .060 .068 8 0 0.20 ref .054 .062 C L E H Pin No. 1 B DETAIL-A h x 45° NOTE: DETAIL-A 1.
