General Description
The EL4094C is a complete two-input fader It combines two
inputs according to the equation
V_OUT ^e V_INA (0 5V ^a Vg) ^a V_INB (0 5V ^b Vg)
where V_GAIN is the difference between V_GAIN and V_GAIN pin
voltages and ranges from ^b0 5V to ^a0 5V It has a wide 60
MHz bandwidth at ^b3 dB and is designed for excellent video
distortion performance The EL4094C is the same circuit as the
EL4095 but with feedback resistors included on-chip to imple-
ment unity-gain connection An output buffer is included in
both circuits
The gain-control input is also very fast with a 20 MHz small-
signal bandwidth and 70 ns recovery time from overdrive
The EL4094C is compatible with power supplies from g5V to
g15V and is available in both the 8-pin plastic DIP and SO-8
