MLX90308CCC is a programmable sensor interface microcontroller, suitable for bridge-type sensors. It features programmable coefficients to reduce non-linearity, compensation for temperature errors with external or internal temperature sensor, versatile output signal ranges, and easy mass calibration.
The MLX90308CCC is a microcontroller‑based signal‑conditioning interface for bridge‑type sensors such as pressure transducers, accelerometers, strain gauges and temperature sensor assemblies. It provides programmable gain, offset, temperature compensation and multiple output options (voltage or 4‑20 mA current) with optional alarm functions.
The document includes electrical specifications, pin descriptions, programming procedures via UART, absolute maximum ratings, and a glossary of terms. It also outlines customization options, ESD precautions and mechanical dimensions of the SO16W package.
