The CA3094 is a high output current operational transconductance amplifier with a frequency bandwidth of 30MHz, which can be used in various circuits
The document describes the CA3094, CA3094A, and CA3094B as differential input power control switches/amplifiers. These devices feature an integral Darlington power transistor capable of sinking or driving currents up to 100mA, making them suitable for directly driving high current thyristors, relays, DC loads, or power transistors.
The gain is programmable via the amplifier bias current (Iabc), allowing sensitivity variation with digital and/or analog signals. The series supports operation from 24V to 44V depending on the specific model (CA3094 for 24V, CA3094A for 36V, and CA3094B for 44V) and includes features for strobing, gating, squelching, and AGC capabilities.
