Description

The MLX90308CCC 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 MLX90308CCC 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.
