The MLX90210 is a discrete micromachined Pressure sensor IC suitable for pressure ranges Between 0 to 1.0 Bar. The pressure medium must be dry and non-corrosive, such as air. The circuit is a piezoresistive bridge which is realized in silicon through a special micromachining process. As pressure is applied to the bridge, a differential voltage change is seen across the Vout pins, while a bias voltage is applied to the Vexc pins.

The Smart Pressure Device SPD series of pressure sensors are silicon based and encapsulated in modified plastic Dual In Line packages, to accommodate six pins for through-board printed circuit mounting. The sensors come in two distinct types: Gauge and absolute. The gauge type merely measures the pressure with respect to the atmospheric pressure. The absolute type contains a reference vacuum chamber, which is formed on the die during manufacturing.
