S E M I C O N D U C T O R CA3080, CA3080A 2MHz, Operational Transconductance Amplifier (OTA) Description The CA3080 and CA3080A types are Gatable-Gain Blocks which utilize the unique operational-transconductanceamplifier (OTA) concept described in Application Note AN6668, “Applications of the CA3080 and CA3080A HighPerformance Operational Transconductance Amplifiers”. The CA3080 and CA3080A types 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 and CA3080A types are notable for their excellent slew rate (50V/µs), 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. PKG. NO.
