alfa rpar AS3381 Dual Low Noise Voltage Controlled Amplifiers (VCA) 

AS3381 is a dual low noise voltage controlled amplifier, with linear scale, intended for applications requiring
high audio performance in a small space. AS3381 contains two gain cells with extremely low noise for signal-tonoise
ratio better than 100 dB, low distortion with less than 0.3% THD, and low control feedthrough for "pop" free
performance when gain modulated.
AS3381 is also extremely easy to use, requiring few external components and no external trimming to meet
their excellent performance. The signal inputs are summing node inputs for convenient signal mixing; and the
control voltage inputs, covering over 100dB with a 5 volt nominal range, are referenced to ground when the
outputs feed virtual ground summing nodes. The current mode outputs offer additional flexibility, allowing AS3381
to be used in high performance VC filters and waveform generators as well as amplifiers.


- two high performance VCAs
- extremely low noise: > 100dB S/N ratio
- low distortion: <0.3% THD
- low feedthrough: <0.3% of full scale output
