LM3080
Operational Transconductance Amplifier
General Description
The LM3080 is a programmable transconductance block in-
tended to fulfill a wide variety of variable gain applications
The LM3080 has differential inputs and high impedance
push-pull outputs The device has high input impedance and
its transconductance (g_m) is directly proportional to the am-
plifier bias current (I_ABC)
High slew rate together with programmable gain make the
LM3080 an ideal choice for variable gain applications such
as sample and hold multiplexing filtering and multiplying
The LM3080N and LM3080AN are guaranteed from 0 C to
a70 C
