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 ma y be used either f or gating or for linear gain control. These types also have a high output impedance and their transconductance (g proportional to the amplifier bias current (I
The CA3080 and CA3080A types are notable for their e xcellent 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.
The CA3080A’s characteristics are specifically controlled for applications such as sample-hold, gain-control, multiplexing, etc.
