The EL4095C 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 ap- pears as the input of a current-feedback amplifier and with ex- ternal resistors can separately provide any gain desired The output is defined as

V _OUT A*V _INA(0. 5V+ V _GAIN)+ B*V _INB  (0.5VV_GAIN ) 

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

Additionally two logic inputs are provided which each override the analog V_GAIN control and force 100% gain for one input and 0% for the other The logic inputs switch in only 25 ns and provide high attenuation to the off channel while generating very small glitches

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

The EL4095C operates from ±5V to ±15V power supplies and is available in both 14-pin DIP and narrow surface mount pack- ages
