www.DataSheet4U.com FHP3350, FHP3450 Triple and Quad Voltage Feedback Amplifiers December 2006 FHP3350, FHP3450 Triple and Quad Voltage Feedback Amplifiers Features ■ 0.1dB gain flatness to 30MHz ■ 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 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. 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. 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 210MH...
