Product Summary

The LM3080N is a programmable transconductance block intended to fulfill a wide variety of variable gain applications. The LM3080N has differential inputs and high impedance push-pull outputs. The LM3080N has high input impedance and its transconductance (gm) is directly proportional to the amplifier bias current (IABC). High slew rate together with programmable gain make the LM3080N an ideal choice for variable gain applications such as sample and hold, multiplexing, filtering, and multiplying.
