Omron 2SMPB-01-01 Absolute Pressure Sensor available at Mouser

Omron's 2SMPB-01-01 Absolute Pressure Sensor can operate in three different power modes: standard, high-accuracy and low-power mode. An I2C interface allows for easy integration into most digital electronics systems. The sensor uses piezoresistance in a full bridge circuit to detect pressure, and requires just two pins to measure differential voltage. This differential voltage output is directly proportional to the measured pressure. Since the voltage is a linear function of the pressure, writing embedded code for the 2SMPB-01-01 is very easy for most microcontroller-based systems. The 2SMPB-01-01 includes a built-in 24-bit, low-noise analogue-to-digital converter (ADC). Each device is factory-calibrated, with the calibration parameters stored in non-volatile one-time programmable (OTP) memory.

The 2SMPB-01-01 has a power consumption of 9uA typical, and is fully temperature compensated with an absolute temperature accuracy of +/-2degC. The low power consumption of the 2SMPB-01-01, along with its compact 3.8mm × 3.8mm × 1.0mm size, makes it suitable for use in a variety of portable low-power battery-operated electronic systems, including wearable electronics, activity monitors, industrial and marine instruments, mobile phones and cameras.

The surface-mount device, also available from Mouser Electronics, is offered in an 8-pin QFN package. Please follow the link to learn more about the 2SMPB-01-01 Absolute Pressure Sensor.
