Mirrocle Bias-Differential Quad-Channel (BDQ) Amplifier 4.x Instructions Manual Download

Page: 3 / 16

Features



Two BNC analog inputs: -10V to +10V



NI-DAQ card compatible, 68-pin connector input



Low power, powered by NI-DAQ card when used or from a
low power 5VDC adapter



Four high voltage output channels, 0V-150V



Outputs differential pairs of 7.5X amplified input voltages
biased at 70V (adjustable internally)



Embedded regulated DC/DC converter creates 156V
supply (Vcc) from the 5VDC input (VDD)



Bandwidth up to 60kHz
