The MLX90323 is a sensor interface IC with 4 to 20 mA current loop output 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 re-programmable. Programming is accomplished by using a PC with an interface circuit (level shifting and glue logic) and provided software.

The robust electrical design allows our MLX90323 to be used where most signal conditioning and sensor interface circuits cannot be used. Voltage regulation control is provided for absolute voltage and current modes (external FET or frozen embryo transfer is required).

The standard package is a plastic SO16W. The device is static-sensitive and requires electrostatic discharge (ESD) precautions.
