0 5V to

0 5V It has a wide 60
MHz bandwidth at

3 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
