Description

The CA3100 is a large signal wideband, high speed
operational amplifier which has a unity gain cross over
frequency (f
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
18V

P-P

±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).

The CA3100 circuit contains both bipolar and PMOS transis­tors on a single monolithic chip.
