Description

The CA3080 and CA3080A types 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 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 (g

proportional to the ampliﬁer bias current (I

The CA3080 and CA3080A types are notable for their excellent

slew rate (50V/ s), 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.
