Description

The CA3100 is a large signal wideband, high speed operational amplifier which has a unity gain cross over frequency (f_T) of approximately 38MHz and an open loop, 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 and 30mA_P-P at the output when operating from ±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.
