General Description
The EL4094C is a complete two-input fader It combines two
inputs according to the equation
VOUT e VINA (05V a Vg) a VINB (05V b Vg)
where VGAIN is the difference between VGAIN and VGAIN pin
voltages and ranges from b05V to a05V 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
g
15V and is available in both the 8-pin plastic DIP and SO-8
