2 General Description
The MLX90326 covers the most typical resistive
type of Wheatstone bridge applications for use in
an industrial or automotive after market
environment. It is a monolithic silicon analog
integrated sensor interface that converts small
changes in resistors, configured in a full
Wheatstone bridge on a sensing element, to large
output voltage variations.
The signal conditioning includes gain adjustment,
offset control and second order temperature
compensation in order to accommodate variations
of the different resistive sensing elements.
Compensation values are stored in EEPROM and
can be reprogrammed with an interface circuit and
a provided software.
The MLX90326 is programmed with a single wire
serial interface through the output pin.
