option is Current Mode, which allows the user a 4mA to 20mA current range to use as a
2-wire analog sensor. These wiring examples as well as technical specifications are shown
in section 4 of this book.
The figures above illustrate to performance of an unconditioned sensor output and a conditioned sensor output
versus stimulus(pressure) and temperature. Notice that figure XXa has a range of only 200mV and has a non-lin-
ear response over a 0-100psi range. The sensitivity of the unconditioned output will also drift over temperature,
as illustrated by the three slopes. The MLX90308 corrects thes errors and also amplifies the output to a more
usable voltage range as shown in figure XXb.
Prototyping with the MLX90308
Melexis has available a MLX90308 evaluation kit
which contains an evaluation circuit board, serial
interface cable, and software diskette. The circuit
board provides the neccessary circuitry for all three
applications circuits shown in the MLX90308
datasheet (section 4 of this book). Also contained on
theboard is level shifting and glue logic necessary
for RS-232 communicatios.
The boaerd has a socket with a single MLX90308
installed, and direct access to the pins of the IC. The
user can easily attach bridge sensor to the board for
in-system evaluation. The serial interface cable
connects the evaluation board directly to a PCs ser-
ial port for in-system calibration.
The software runs in the familiar Windows platform
and allows for programming and evalution of all
compensation parameters within the EEPROM of
the MLX90308.
