Overview

The SMI 1000/SMI 4000 are medium pressure MEMS sensors from 2.5 to 30 PSI available in gauge, differential and asymmetric differential configuration. 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. 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.

APPLICATION NOTE

Sleep Mode And Other Low Power Strategies (English)

The SMI 1000 and SMI 4000 series digital output sensors earned the AccuStable quality label. The AccuStable brand stands for <1% total error band initially and <1% shift during operation over a 10 year lifetime. Qualification is based on 1,000 hours HTOL (High Temperature Operating Life) test at 85°C with 5V.

FAQ

FREQUENTLY ASKED QUESTIONS

What is the proof pressure (maximum pressure to which the device can be taken and still perform within specifications (without loss of accuracy) after returning to the operating pressure range) for the SMI 1000 and SMI 4000 Series?

The proof pressure for sensors with a maximum operating pressure range up to 7.5 PSI is 25 PSI, respectively 45 PSI for devices with a maximum operating pressure range up to 30 PSI.

What is the burst pressure (pressure where part is permanently damaged) of the SMI 1000 and SMI 4000 Series?

The burst pressure for sensors with a maximum operating pressure range up to 7.5 PSI is 40 PSI, respectively 75 PSI for devices with a max operating pressure range up to 30 PSI.
