Features & Applications
Compared to digital sensors, this is where the extra design scope becomes obvious – parallel analog output of measured values as three voltage levels is proportional (ratiometric) to momentarily measured acceleration, offering a maximum of motion data. No integrated analog/digital converters or multiplexer to serialize measured data impacts resolution capability and speed of reaction of this parallel analog signal path. That provides the designer the freedom to use external ADCs, multiplexers and filters exactly attuned to product requirements. In this way specific motion patterns can be detected with extremely high accuracy while unwanted ones are rejected.
In addition to three parallel outputs, BMA145 feature a flexible serial analog output by leveraging an integrated multiplexer. By directing acceleration signals to a single-channel A/D converter, engineers can achieve lower system costs without sacrificing performance. A flexible use of signal outputs makes the two new analog sensors suitable for detecting motion and position in a variety of mobile c
