MLX90314

Description

The MLX90314 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 MLX90314 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.
