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 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/?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 generalpurpose, 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.
