Description
Data Conversion IC Development Tools Evaluation Kit for the MAX155
Manufacturer
Maxim Integrated
Series
MAX155, MAX156r
Datasheet
The MAX155 evaluation kit (EV kit) is a functional 8-
channel, 8-bit data-acquisition system. The printed cir-
cuit board has an 80C32 microprocessor controlling the
MAX155 analog-to-digital converter. Software run on an
IBM-compatible personal computer communicates over
an RS-232 link to perform analog-to-digital conversions
and display the results.
The input channels can be configured in a variety of
combinations of single-ended/differential and
unipolar/bipolar modes. All input channels are sampled
simultaneously at the beginning of each conversion for
low skew between channels. A single channel can be
selected for conversion and display, or all channels can
be read.
The board operates from a single 6V to 12V supply. A
MAX660 generates the -5V supply needed for converting
voltages below ground.
