1. An integrated circuit for processing biosignals, the integrated circuit comprising:
a digital conversion unit for converting an analog biosignal input through a biosignal input terminal into a digital biodatas; and
an Artificial Intelligence (AI) block for processing a plurality of biodatas converted through the digital conversion unit according to an artificial intelligence processing flow, and outputting result data according to processing of the plurality of biodatas,
wherein the digital conversion unit includes:
a demultiplexer for outputting an analog biosignal output from the biosignal input terminal to a first output line or a second output line according to a type signal that is input through a type input terminal;
a trans-impedance amplifier for amplifying the analog biosignal of the first output line and outputting the amplified biosignal;
a low-noise amplifier for amplifying the analog biosignal of the second output line and outputting the amplified biosignal; and
a first multiplexer for outputting a biosignal selected from the biosignal of the trans-impedance amplifier and the biosignal of the low-noise amplifier according to the type signal.
