EL4094 pdf datasheet (Video Ga

The EL4094 is a complete two-input
fader. It combines two inputs according
to the equation:
VOUT = VINA (0.5V + VG) + VINB (0.5V - VG),
where VGAIN is the difference between VGAIN and VGAIN
pin voltages and ranges from -0.5V to +0.5V. It has a wide
60MHz bandwidth at -3dB, and is designed for excellent
video distortion performance. The EL4094 is the same circuit
as the EL4095, but with feedback resistors included on-chip
to implement unity-gain connection. An output buffer is
included in both circuits.
The gain-control input is also very fast, with a 20MHz smallsignal
bandwidth and 70ns recovery time from overdrive.
The EL4094 is compatible with power supplies from ±5V to
±15V, and is available in both the 8-pin plastic DIP and
SO-8.
