SM7421 Datasheet | Silicon Microstructures

Low Pressure Digital Sensor SM7221, SM7321, SM7421 Series Gauge & Differential Pressure Sensors Features - Pressure ranges from 0.15 to 0.29 psi; gauge, differential and asymmetric outputs - Accuracy: ±1% full scale - 14-bit digital, pressure calibrated and temperature pensated output - I2C Digital Interface - pensated temperature range: -20 to 85o C - Insensitive to mounting orientation - Robust JEDEC SOIC-16 package for automated assembly - Manufactured according to ISO9001 and ISO/TS 16949 standards DESCRIPTION The SM7221, SM7321 & SM7421 series is a digital, low pressure MEMS sensor family offering state-of-the-art pressure transducer technology and CMOS mixed signal processing technology to produce a digital, fully conditioned, multi-order pressure and temperature pensated sensor in JEDEC standard SOIC-16 package with a dual vertical porting option. It is available in both pound gage or differential pressure configurations. With the dual porting, a vacuum-gage measurement is possible to minimize altitude errors due to changes in ambient pressure. bining 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 pensation network or microcontroller containing a custom correction algorithm. Customer-specified pressure ranges and supply voltages are available. The SM7221, SM7321 & SM7421 series is shipped in sticks or tape & reel.
