ALFA RPAR AS3080 OTA IC - CA3080 Replacement


The AS3080E is a gain block which is the operational-transconductance-amplifier (OTA). The 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-tonoise improvement referenced to 0,5 percent THD. The AS3080E is notable for it’s high slew rate (50V/µs), 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. 

The AS3080 is available in DIP8 thru-hole and SOIC8 SMT configurations
