Altimeter with 13cm resolution "MS5637-02BA03"

TE Connectivity's MS5637-02BA03 is an ultra-compact altimeter with a size of only 3m x 3m. Equipped with a 24-bit ΔΣ ADC for highly accurate measurement.

Altitude can be measured accurately over a wide range of 300-1200mbar. Also, the conversion speed and current consumption can be controlled via IC.

Therefore, it is ideal for applications such as smartphones and tablet PCs that require narrow spaces and high functionality.

In this article, we will explain the following major features and benefits of the MS5637-02BA03.

1. Resolution at sea level is 13 cm
2. Ultra-compact package of only 3m x 3m
3. Built-in I2C enables easy connection with a microcomputer
4. Ultra-low power consumption, ideal for battery applications

1. Resolution at sea level is 13cm

A typical altimeter resolution is 30cm or better. The resolution of MS5637-02BA03 is 13 cm, which is less than half that of a general altimeter.

This is because the MS5637-02BA03 is equipped with a high linearity pressure sensor and a 24-bit ΔΣ ADC, enabling high-resolution measurements.
High-resolution altitude and temperature outputs allow the implementation of altimeter and thermometer functionality without additional sensors.

2. Ultra-compact package of only 3m x 3m

Ultra-small QFN package 3mm x 3mm.
It is the perfect device for narrow applications such as smartphones and tablets where mounting space is limited.

3. Built-in I2C enables easy connection to a microcomputer

MS5637-02BA03 has an I2C interface. It can be easily connected to a general microcomputer equipped with an I2C bus.

Therefore, it is possible to realize development and commercialization in a short period of time.

Application example

• smartphone
• tablet pc
• personal navigation device
