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 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.
