CA3080EZ + Socket - Operational-Transconductance Amplifier



The CA3080 OTAs are Gatable-Gain Blocks which utilize the unique operational-transconductance amplifier (OTA) concept described in Application Note AN6668, "Applications of the CA3080 and CA3080A High-Performance Operational Transconductance Amplifiers".

The CA3080 OTAs 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).

The CA3080 OTAs are notable for their excellent slew rate (50V/us), which makes them especially useful for multiplexer and fast unity-gain voltage followers. These types are especially applicable for multiplexer applications because power is consumed only when the devices are in the "ON" channel state.
