Digitimer provides the NL143 Three Channel Difference Amplifier. This is a Three Channel, or differential, amplifier with 4-channels of input. Internal selection allows the difference between any of the four input channels to be made by this Three Channel Amplifier.
With the NL143 Three Channel Difference Amplifier, internal preset controls (which are finger operated) allow an offset to be nulled or added as required. High input protection allows for signals coming from units that are not part of the NeuroLog System.
