Unique Features
Customization
Melexis
can
customize
the
MLX90308
in
both
hardware and firmware for unique requirements. The
hardware design provides 64 bytes of RAM, 3 kbytes
of ROM, and 48 bytes of EEPROM for use by the
firmware.
Special Information
The output of the sensor bridge is amplified via offset
and gain amplifiers and then converted to the correct
output signal form in one of the output stages.
The sensitivity and offset of the analog signal chain
are defined by numbers passed to the DAC interfaces
from the microcontroller core (GN[9:0] and OF[9:0]).
The
wide
range
of
bridge
offset
and
gain
is
accommodated by means of a 2-bit coarse adjustment
DAC in the offset adjustment (CSOF[1:0]), and a
similar one in the gain adjustment (CSGN[2:0]). The
signal path can be directed through the processor for
digital processing. Two I/O pins are available for
analog inputs or digital outputs. These pins can be
used for alarms on various points on the analog signal
path and built-in or external temperature values.
Programming and Setup
The MLX90308 needs to have the compensation
coefficients programmed for a particular bridge
sensor
to
create
the
sensor
system.
Programming
the
EEPROM
involves
some
minimal
communications
interface
circuitry,
Melexis’
setup
software,
and
a
PC.
The
communications interface circuitry is available in
a
de ve lopm ent
b oar d.
T his
circuitr y
communicates with the PC via a standard RS-
232 serial communications port.
Cross Reference
There are no known devices which the MLX 90308
can replace.
ESD Precautions
Observe standard ESD control procedures for CMOS
semiconductors.
