LPA400 User Guide Specification Parameter LPA 400A LPA 400B Units isolated BNC Input connector Input impedance Peak operational input 3.6 8 voltage Maximum safe input 15 voltage Input common mode 40 range Input offset voltage mV (typ) mV(max) ac, ac+dc, ac+(dc) Input coupling (switch) AC coupling filter –3dB (DC) gain factor... - Page 6 LPA400 User Guide Note:The amplifier contains an output rms current protection circuit, and when driving some capacitive loads this circuit may be activated. Due to capacitor construction, at high current the amount of energy transfer distorts the current waveform resulting in excessive peak current (Fig 1 below), whilst the rms value remains within specification.
