AS3080E

The ALFA AS3080E is a gain block which is the operational-transconductance amplifier (OTA). The ALFA AS3080E have differential input and a single-ended, push-pull, class A output. Amplifier bias input may be used either for gating or for linear gain control. High output impedance and transconductance (Gm) is directly proportional to the amplifier bias current (Iabc). Linearizing diodes are provided at the inputs to reduce distortion and allow higher input levels. The result is a 10-dB signal-to-noise improvement referenced to 0,5 percent THD. The ALFA AS3080E is notable for it's high slew rate (50V/us), which makes it especially useful for multiplexer and fast unity-gain voltage followers. It is especially applicable for multiplexer applications because power is consumed only when the devices are in the 'ON' channel state. PDIP-8.
