MLX90326 Analog 0-5V Sensor Interface IC Features and Benefits Analog 0-5V ratiometric output Single pin programming (through output) Fast response time Extended temperature range Cost effective “electronic trimming” Second order compensation of offset and gain Internal temperature sensor provided Application Examples Pressure transducers, strain gauges, accelerometers, position sensors, etc… Industrial sensors Automotive after market sensors All resistive bridge sensors Ordering Information Part No. MLX90326LFR Temperature Code L (-40° C to 150°C) Package Code FR (SSOP 209 mil) 1 Functional Diagram 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. www.DataSheet4U.com 3901090326 Rev 002 Page 1 of 13 Data Sheet Jan/08 MLX90326 Analog 0-5V Sensor Interface IC Table of...
