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 re-

programmable. Programming is accomplished by using a PC, with an interface circuit (level shifting and glue

logic), and provided software.

The application circuits can provide an

output of an absolute voltage, relative

voltage, or current. The output can be

range limited with defined outputs when the

signal is beyond the programmed limits.

Other features include alarm outputs and

level steering. The robust electrical design

allows the MLX90308CAB 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

required).

The standard package is a plastic SO16W.

The device is static-sensitive and requires

ESD precautions.
