Features • Slew rate (unity gain compensated): 50 V/µs • Fully adjustable gain: 0 to gm • RL limit • Extended gm linearity: 3 decades • Flexible supply voltage range: ±2V to ±18V • Adjustable power consumption Description The LM3080 is a programmable transconductance block intended 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 (gm) is directly proportional to the amplifier bias current (IABC). 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 +70°C.
