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:

where A and B are the fed-back gains of each channel.

Additionally, two logic inputs are provided which each

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.
