2MHz, Operational Transconductance

Amplifier (OTA)

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

The CA3080 and CA3080A types are notable for their excellent

slew rate (50V/µs), which makes them especially useful for

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.
