2MHz, Operational Transconductance
Ampliï¬er (OTA)
The CA3080 and CA3080A types are Gatable-Gain Blocks
which utilize the unique operational-transconductance-
ampliï¬er (OTA) concept described in Application Note
AN6668, âApplications of the CA3080 and CA3080A High-
Performance Operational Transconductance Ampliï¬ersâ.
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 âONâ
channel state.
The CA3080Aâs characteristics are speciï¬cally controlled for
applications such as sample-hold, gain-control, multiplexing,
etc.
