The Programmable Sensor Interface
A microcontroller sensor interface provides signal conditioning for a sensor element of any kind. Some types of
sensor elements that can be used are pressure sensors, strain gauges, load cells, thermistors, and potentiometers
(position sensing).
The MLX90308 sensor interface provides control over the offset, gain (or sensitivity), linearity and temperature
compensation of the sensors signal using a microcontroller.
In the past, such conditioning was done through discrete circuits. Such circuits required costly and unreliable
trimming methods, not to mention component count on the PC board. Because the MLX90308 is a microcon-
troller, calibration is done digitally through a standard PC. The MLX90308 contains an 8-bit RISC core micro-
controler, analog signal path, supply regulator, and EEPROM for storing compensation coefficients.
Figure 29 illustrates a fundamental application of the MLX90308 and a bridge type pressure sensor element. In
this application, the 90308 uses an external FET as a pass transistor to regulate the voltage to the sensor and the
analog portion of the IC. This is known as Absolute Voltage Mode, where voltage to the sensor and analog cir-
cuit is regulated, independent of the supply voltage. The 90308 can be operated in Ratiometric Voltage Mode,
where the output (VMO) is tied to an A/Dconverter sharing the same Supply and GND reference. A third wiring
