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 AS3080ED is notable for it’s high slew rate (50V/µs), which makes it especially useful for multiplexer and fast unity-gain voltage followers. $4.75 OTA - AS3280D, Dual, Linearizing Diodes, Alfa, SOIC-16 The AS3280 is Alfa’s version of the CA3280 IC in an SOIC package. The AS3280D consists of two variable operational amplifiers that are designed to substantially reduce the initial input offset voltage and the offset voltage variation with respect to changes in programming current. This design results in reduced "AGC thump," an objectionable characteristic of many AGC systems. Careful design of critical places of the circuit reduces the amplifier dependence upon thermal and processing variables. The AS3280D has all the generic characteristics of an operational voltage amplifier except that the forward transfer characteristics is best described by transconductance rather than voltage gain, and the output is current, not voltage. The magnitude of the output current is equal to the product of transconductance and the input voltage.$7.95 OTA - AS3080E, Linearizing Diodes, Alfa, 8-Pin DIP The AS3080E is Alfa’s version of the CA3080 IC.
