Description
The MLX90308CAB is a dedicated microcontroller
which performs signal conditioning for sensors wired
in bridge or differential configurations. Sensors that
can be used include thermistors, strain gauges, load
cells, pressure sensors, accelerometers, etc. The
signal conditioning includes gain adjustment, offset
control,
high
order
temperature
and
linearity
compensation. Compensation values are stored in
EEPROM and are re-programmable. Programming is
accomplished by using a PC, with an interface circuit
(level shifting and glue logic), and provided software.
The application circuits can provide an output of an
absolute voltage, relative voltage, or current. The
output can be range limited with defined outputs
when the signal is beyond the programmed limits.
Other features include alarm outputs and level
steering. The robust electrical design allows the
MLX90308CAB to be used where most signal
conditioning and sensor interface circuits cannot be
used. Voltage regulation control is provided for
absolute voltage and current modes (external FET
required).
The standard package is a plastic SO16W. The
device
is
static-sensitive
and
requires
ESD
precautions.
