Description
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 V
out
pins, while a bias voltage is
applied to the V
exc
pins.
The MLX90210 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.

Reliability Information
Melexis devices are classified and qualified regarding suitability for infrared, vapor phase and wave
soldering with usual (63/37 SnPb-) solder (melting point at 183degC).
The following test methods are applied:
IPC/JEDEC J-STD-020A (issue April 1999)
Moisture/Reflow Sensitivity Classification For Nonhermetic Solid State Surface Mount Devices
CECC00802 (issue 1994)
Standard Method For The Specification of Surface Mounting Components (SMDs) of Assessed Quality
MIL 883 Method 2003 / JEDEC-STD-22 Test Method B102
Solderability
For all soldering technologies deviating from above mentioned standard conditions (regarding peak
temperature, temperature gradient, temperature profile etc) additional classification and qualification tests
have to be agreed upon with Melexis.
The application of Wave Soldering for SMD's is allowed only after consulting Melexis regarding assurance
of adhesive strength between device and board.
