Digital Pressure Sensor XY100A

Digital Pressure Sensor XY100A Brief Introduction

    XY-PS100A is a high precision barometer and altimeter especially designed for consumer applications. It measures the pressure based on piezo-resistive MEMS
pressure sensor.
The ultra-low power, low voltage of the XYPS100A is optimized for use in mobile phones, smart watches, PDAs, GPS navigation devices and outdoor equipment.
The sensor module is housed in a compact 8- pin metal-lid LGA package with a footprint of only 2 . 0 × 2 . 5 mm2 and 1.0mm package height. Its small dimensions
and its low power consumption allow the implementation in battery driven devices.With a low altitude noise of merely 0. 1m and very low offset temperature coefficient
(TCO), the XY-PS100A offers superior performance and are perfectly suitable for applications like floor detection, health care as well as GPS refinement. The I2 C interface
allows for easy system integration with a MCU.
