Video Gain Control/Fader
The EL4094 is a complete two-input
fader. It combines two inputs according
to the equation:
V_OUT = V_INA (0.5V + V_G) + V_INB (0.5V - V_G),
where V_GAIN is the difference between V_GAIN and V_GAIN
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 small-
signal 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.
