The FHP3130 (single), FHP3230 (dual), and FHP3430 (quad) low-cost, high-performance, voltage feedback amplifiers consume only 2.5mA of supply current channel each while delivering ±100mA of output current. These amplifiers are designed to operate from 2.7V to 12V (±6V) supply. The common-mode voltage range includes the negative rail and the output provides rail-to-rail performance. The FHP3130, FHP3230 and FHP3430 are designed in a free bipolar process and provide a 170MHz supply voltage of 5V. The combination of low power, rail-to-rail performance, low voltage operation and tiny package options these amplifiers are ideal for use in many general purpose high speed applications. These amplifiers also offer excellent video specifications. They offer extremely low differential gain and phase (0.008%/0.01°) and 0.1dB gain flatness to 10MHz for excellent standard definition video performance. Their output drive capability supports four video loads with no effort.

Application Information: Frequency Response vs. CL plots in Driving Capacitive Loads diagram illustrating the response of the FHP3230 series. Small series resistance (Rs) at the amplifier output, as shown, improves stability and settling performance. The value of Rs in the frequency response selects the CL curve for maximum bandwidth. The peak value is less than 1dB. For maximum flatness, use a larger Rs

Power dissipation The maximum allowable internal power dissipation is directly related to the maximum junction temperature. If the maximum junction temperature exceeds 150°C. Over time, equipment failure may occur. The FHP3130, FHP3230, and FHP3430 are short-circuit protected; however, this may not guarantee that the maximum junction temperature (±150°C) is not exceeded under any circumstances. RMS power dissipation can be calculated using the following formula: where 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 graph shown to ensure proper operation.

Overspeed recovery for amplifiers when the output and/or input range is exceeded. The resuscitation time varies depending on whether the input or output is too fast and how far it is out of range. The FHP3130/3230/3430 are typically overspeeding in less than 50 ns. The diagram shows the FHP3230 in overdrive.

The composite video camp bandwidth and differential gain/phase performance are suitable for video applications in the FHP3130/3230/3430 amplifiers. Figure shows a typical composite video summary. High output current capability allows driving multiple video loads. Diagram showing differential gain/phase for three amplifier configuration driving four video loads (or 37.5W)

Layout Considerations General layout and supply bypass play a major role in high frequency performance. Fairchild has evaluation guides for board testing and characterization of high frequency layouts and auxiliary equipment. Follow these guidelines as a basis for high frequency layout: Include 6.8µF and 0.01µF ceramic capacitors. Place 6.8µF capacitors at the power pins. Place 0.01µF capacitors at the power pins. Remove ground planes under and around parts, especially near input and output pins, to reduce parasitic capacitance. Minimize all trace lengths to reduce series inductance.

Evaluation Board Information The following evaluation boards are available to aid in the testing and layout of these devices:
