The NL104A AC Pre Amplifier from Digitimer is a low noise AC coupled differential amplifier (Extracellular Amplifier) from our Amplifier Module range.

It can be used alone for making in vitro or in vivo recordings from low resistance electrodes or with the NL100AK head stage (or NL100AKS & NL100C) for extracellular microelectrode recording. The NL104A AC Preamplifier has a facility to restrict the high-frequency response (a jumper on the printed circuit board, with -3dB limits indicated) eradicating the necessity for consequent filtering in some applications.

It can be operated in single-sided (inverting or non-inverting) or differential modes has a wide dynamic balance adjustment for asymmetrical inputs. This is useful for balancing out interference and short artefacts, a choice of two input time constants and eight gains.
