Description
• High Open Loop Gain at Video
The CA3100 is a large signal wideband, high speed
Frequencies . . . . . . . . . . . . . . . . . . 42dB (Typ) at 1MHz operational amplifier which has a unity gain cross over
frequency (f ) of approximately 38MHz and an open loop,

• Unity Gain
3dB corner frequency of approximately 110kHz. It can
operate at a total supply voltage of from 14V to 36V (±7V to
±18V when using split supplies) and can provide at least
Crossover Frequency (f ) . . . . . . . . . . . . . 38MHz (Typ)

±15V supplies. The CA3100 can be compensated with a
single external capacitor and has DC offset adjust terminals
for those applications requiring offset null. (See Figure 1).
