Analog, triaxal acceleration sensor
Bosch Sensortec
General description
The BMA140 is an analog, triaxial low-g acceleration
sensor for consumer market applications, available in
a super-flat land-grid array (LGA) package with a very
small footprint of 3mm x 3mm and a height of merely
0.9mm. It allows measurements of static as well as
dynamic accelerations. Due to its three perpendicu-
lar axes it gives the absolute orientation in a gravity
field and enables free-fall detection.
The BMA140 is a two-chip arrangement, which com-
bines an application-specific integrated circuit (ASIC)
with a three-channel silicon accelerometer, to form a
true micro electro mechanical system (MEMS).
This concept and the advanced micromachining tech-
nology have proven their robustness and reliability
in more than 150 million Bosch MEMS sensors per
year. The modular ASIC design provides the flexibili-
ty to react quickly to customer needs for additional
sensor functionality in the future.
The BMA140 provides three parallel analog output
signals in a ±4g acceleration range. In addition to the
parallel X, Y and Z output signals there is the option to
multiplex any axis to a single supplementary output
pin in a freely customized manner.
