Description

The CA3100 is a large signal wideband, high speed

operational amplifier which has a unity gain cross over

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

±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 transis-

tors on a single monolithic chip.
