Description

The FHP3350 and FHP3450 are low-cost, high-performance, voltage-feedback amplifers designed for video applications. These triple and quad amplifers 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 beneft 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.
