Medium Pressure Sensor 27 45 131 Digital Output 167 AccuStable SM3041 Series 170 175 FEATURES 169 0 Fully digital, pressure calibrated and temperature compensated 61 output 2 I C Digital Interface o Compensated temperature range: -20 to +85 C Better than 1% initial accuracy and less than 1% accuracy shift over life (<1% shift over 1000hr HTOL) Differential pressure configuration Custom pressure ranges available Insensitive to mounting orientation Manufactured according to ISO9001 and ISO/TS 16949 standards Pressure ranges from -15 to 15 PSI DESCRIPTION Combining the pressure sensor with a signal-conditioning ASIC in a The SM3041 Series is a digital, medium pressure MEMS sensor single package simplifies the use of advanced silicon micro-machined family offering state-of-the-art pressure transducer technology pressure sensors. The pressure sensor can be mounted directly on a and CMOS mixed signal processing technology to produce a standard printed circuit board and a high level, calibrated pressure digital, fully signal conditioned, multi-order pressure and signal can be acquired from the digital interface. This eliminates the temperature compensated sensor in JEDEC standard SOIC-16 need for additional circuitry, such as a compensation network or package with a dual vertical porting option. It is available as a microcontroller containing a custom correction algorithm. differential sensor or with custom pressure ranges. The SM3041 is shipped in sticks or tape & reel.
