Installed in the MLX90614 are a low-noise amplifier and 17-bit ADC and powerful DSP. This enables the high-accuracy and resolution of the thermometer. The MLX90614 comes factory calibrated with a digital SMBus output that gives full access to the measured temperature in the complete temperature range(s) with a resolution of 0.02°C.
The digital output can be configured to be PWM. The 10-bit PWM is configured to continuously transmit the measured temperature in the range of -20 to 120°C, with a 0.14°C output resolution.
