Product Description
The AMP4CH-DF is a 4 channel amplifier for use with differential
inputs like those needed to drive the PAR4CH 24-bit data acquisition
system. In its standard configuration, the AMP4CH-DF provides a gain
of 100 on each analog input channel while using only 120 ma.
The AMP4CH-DF allows high resolution acquisition of very small
signals. With its standard x 100 gain, the AMP4CH-DF allows signals as
small as +/- 100 millivolt to span the full +/- 10 volt analog input
range of the PAR4CH. Designed with extremely good noise
characteristics, the AMP4CH-DF adds almost no detectable noise to the
final acquired data.
The AMP4CH-DF comes with all the accessories you need. These
include an enclosure that stacks nicely with the PAR4CH and the power
and D-shell cables for connecting to the PAR4CH. All you supply are
the analog inputs.
The gain on each channel is controlled by a resistor.
Soldering on a different resistor changes the gain. Custom gain
configurations are available for a small fee when placing your order.
