The SM4000/SM1000 are medium pressure MEMS sensors offering
state-of-the-art pressure transducer technology and CMOS mixed
signal processing technology to produce either an analog and/or digital
output fully conditioned, multi-order pressure and temperature
compensated. This series provide a JEDEC standard SOIC-16
package with vertical or horizontal porting options or a JEDEC SOIC-10
package with a vertical port. It is available in gage, differential and
asymmetric differential configurations. With the dual porting, a
reference measurement is possible to minimize errors due to changes
in ambient pressure.
Combining the pressure sensor with a signal-conditioning ASIC in a
single package simplifies the use of advanced silicon micro-machined
pressure sensors. The pressure sensor can be mounted directly on a
standard printed circuit board and a high level, calibrated pressure
signal can be acquired from the digital interface. This eliminates the
need for additional circuitry, such as a compensation network or
microcontroller containing a custom correction algorithm.
Customer-specified pressure ranges and supply voltages are
available.
The SM4000/SM1000 are shipped in sticks or tape & reel.
The SM4000 and SM1000 digital output only
sensors earned the AccuStable quality label.
The AccuStable brand stands for <1% total error
band initially and <1% shift during operation over
10 year lifetime. Qualification is based on 1000
hours HTOL (High-temperature operating life)
test at 85°C with 5V.
