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 reprogrammable. Programming is accomplished by using a PC, with an interface circuit (level shifting and glue logic), and provided software.

Features and Benefits

Versatile output signal ranges: 4, 5, 10, or 11VDC; 4 to 20 mA loop

Mass calibration easy with 2400 or 9600 baud UART

Power supply from 6 to 35VDC

Applications

Pressure transducers

Accelerometers

Temperature sensor assemblies

Linear position sensors
