The CA3080EZ are Gatable-Gain Blocks which utilize the unique operational-transconductance amplifier (OTA) concept. The CA3080EZ have differential input and a single-ended, push-pull, class A output. In addition, these types have an amplifier bias input which may be used either for gating or for linear gain control. These types also have a high output impedance and their transconductance (gM) is directly proportional to the amplifier bias current(IABC).
