The E703.21 is a fully integrated pressure signal conditioner. Its analog sensor front end directly interfaces to a wide range of pressure sensors. Pressure and temperature values are corrected by a DSP with a multi dimensional polynomial using up to 16 coefficients. The corrected values are available via an I²C or SPI interface. In parallel the pressure value is also available as an absolute voltage, ratometric voltage or current signal. The supply and analog output pins are fully protected against reverse polarity, over voltage and short circuit with minimal external circuitry.
