EL4095: Video Gain Control/Fader/Multiplexer

The EL4095 is a versatile variable-gain building block. At its core is a fader which can variably blend two inputs together and an output amplifier that can drive heavy loads. Each input appears as the input of a current-feedback amplifier and with external resistors can separately provide any gain desired. The output is defined as: VOUT = A*VINA (0. 5V + VGAIN) + B*VINB (0.5V-VGAIN), where A and B are the fed-back gains of each channel. Additionally, two logic inputs are provided which each override the analog VGAIN control and force 100% gain for one input and 0% for the other. The logic inputs switch in only 25ns and provide high attenuation to the off channel, while generating very small glitches.

Signal bandwidth is 60MHz, and gain-control bandwidth 20MHz. The gain control recovers from overdrive in only 70ns.

The EL4095 operates from ±5V to ±15V power supplies, and is available in both 14-pin DIP and narrow surface mount packages.
