    An LM393 is a 8-pin chip. The pinout is shown below: The LM393 has 2 power inputs. These are labeled Vcc and GND. Vcc is where the positive terminal of the voltage supply gets inserted into. This supply voltage can be as high as 36V. GND is where the ground wire of the voltage source gets connected to.

process audio with an LM393 : harder than it seems ...

    Hi all, I'm trying to use an LM393 as a "positive detector" on two audio signals. I mean that when the audio signal from the pre-amp is above 0 volts the LM393 should produce an arduino-compatible "1" (or "0"). the audiosignal is produced by the pre-amp using a 2.2uF cap in series, so what I get is a pure ac wave without DC bias.

    Intro to Amplifier Comparator Circuits: LM311, LM393, LM2903 and LM2901. In electronics, the comparator is a circuit that makes use of operational amplifiers with very high gain in its open-loop state. The **op-amp comparator** has a positive or negative voltage output by comparing its input voltage against some DC reference voltage.
