Video Gain Control/Fader

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 VGAINis the difference between VGAINand 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 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.
