Description
The MLX90240 is a discrete
micromachined
pressure sensor IC suitable for pressure ranges
between 0 to 350mBar. The pressure medium must
be dry and non-corrosive, such as air.
The 90240 is packaged in a plastic/ceramic
package, (CA) or can be ordered as unpackaged die
(UD) The principal of the circuit is a piezoresistive
bridge which realized in silicon through a special
micromachine process. As pressure is applied to the
bridge, a differential voltage change is seen across
the V
OUT
pins, while a bias voltage is applied to the
V
EXC
pins.
The MLX90240 is a versatile pressure sensor
solution which can be directly interfaced with other
Melexis ICs such as the MLX90308, which provides
amplification, signal conditioning as well as the bias
current to supply the sensor itself.
