Isolated Differential Amplifier The improved ISO-80 provides low noise AC coupled amplification and offers excellent recording performance for monitoring extracellular nerve action potentials in vitro and in living animals. The ISO-80 is provided with a remote headstage (1 m cable) which incorporates an electrode impedance test function and a constant current stimulator. The constant current stimulator can be used for cell marking, stimulation or electrode cleaning. Typical applications include measuring EMG, EEG, extracellular and action potentials in vitro or in vivo. The ISO-80 system is DC isolated from the subject ground and employs state of the art electro-magnetic shielding for improved noise rejection. The amplifier employs both high pass and low pass filtering with gain from 100 to 10,000. The lowest low-pass setting is 5Hz and the upper passband is 10 kHz.
