The DIN and Bio Amp inputs are both differential inputs suitable for selected extracellular recordings.
The Bio Amp input is more sensitive than the DIN inputs. Consequently a potential issue is that signals recorded via the Bio Amp input may be more noisy due to this increased sensitivity.
The MAXIMUM input voltage that can be applied to a Bio Amp is less than the maximum input voltage for a DIN input. Therefore, the user must be careful not to overload the input circuit.
If stimulation is being provided to the nerve, it would be preferable to use a DIN input (not a Bio Amp input).
Currently, ADInstruments supply the Nerve Chamber with two MLA285 Differential Pod Input Cables (DIN to Micro-Hooks) for recordings using the PowerLab Pod ports. This is found to be most suitable in most cases.
