Specs are approved by the manufacturerAttenuverter, Mixer, Comparator, voltage source
The AV3 is a dual attenuverter, voltage source, mixer and comparator combined. You can use the functions by them selves or combined.
The combination of simple functions makes this a very useful module to have in your toolbox.
It can be used for control signals or for audio.
The bandwidth of the AV3 is more than 300 kHz. This makes it suitable for clean audio operation like mixing or subtracting signals without adding any frequency dependent phase shift.
These merchants probably sell this module. Huh?
