Functional Diagram Description 1.2 to 3 Bar Full Scale VDD Chopper demodulator Gain calibration Temperature sensor ADC DIGITAL CORE DAC 2. Description The MLX90269 is an integrated absolute pressure sensor (0 Bar = vacuum) realized in CMOS OUT technology with micromachining options. It consists of an analog signal chain that interacts with the digital core and on-chip temperature sensor in order to provide uniform overall sensing characteristics after calibration and to cancel the temperature related parameter drifts. Diagnostics The output is proportional to the applied pressure with an adjustable slope and offset. It is ratiometric and goes rail-to-rail with a 3mA source and sink capability. Different pressure ranges are available (from 1.2 to 7 Bar full scale ranges, see above ordering informatio...
