Qualified for automotive applications The ADXL185B z-axis sensor and the ADXL189B x-axis sensor
are g range configurable, integrated single-axis satellite sensors,
compliant with the PSI5 Version 1.3 specification. The ADXL185B/
ADXL189B enable low cost solutions for front and side impact
airbag satellite sensor applications. Acceleration data is sent to
the control module via a digital 2-wire current loop interface bus.
The sensor g range is configurable to provide full-scale ranges …
