Note Specifications within this document are subject to change without notice. BMA140 Data sheet Triaxial, analog acceleration sensor Bosch Sensortec The BMA140 in general The BMA140 is a triaxial low-g acceleration sensor for consumer market applications, available in a standard SMD LGA package with a footprint of 3x3mm2 and a height of only 0.9mm. It allows measurements of static as well as dynamic accelerations. Due to its three perpendicular axes it gives the absolute orientation in a gravity field and enables free fall detection. As all other Bosch inertial sensors, the BMA140 is a two-chip arrangement, which combines an application-specific integrated circuit ASIC with a three-channel silicon accelerometer, to form a true micro electro mechanical system MEMS . The ASIC evaluates the output of the acceleration-sensing element, corresponding to the differential capacitance principle. The underlying MEMS technology processes have proven their capability according to the strictest automotive standards in more than 100 million Bosch inertial sensors a year so far. The BMA140 provides 3 parallel analog output signals in a ±4g acceleration range. All acceleration signals are permanently available on 3 independent analog pads through resistors on each pad. This allows the user defining the signal bandwidth by the mean of external capacitors connected between each channel output and ground. Additional to the parallel X, Y and Z output signals there is the option to multiplex any axis to one supplementary output pin in a freely customized manner. This allows the user to connect the triaxial BMA140 to an economical single channel AD converter without loss of axis information. For each axis, an independent analog kHz 1st-order low-pass filter is included to provide preconditioning of the measured acceleration signal. The corner frequency of this filter can easily be customized. Additional signal preconditioning steps are performed by a digital to analog converter for offset and gain correction purposes with a subsequent signal amplification. The output signals are ratiometric. In the ±4g acceleration range the sensor is offering a sensitivity of 300mV/g at V supply voltage VDD / 10 and as a typical noise level. The typical current consumption is 200µA in operation. Furthermore, the sensor can be switched into a standby mode via supplementary selection pins. In standby mode the sensor module features an ultra low current consumption of typically µA. The return from standby mode to full performance conditions is performed in less than 1ms wake up time. The BMA140 sensor module is ready to use due to test and calibration at factory level. All calibration parameters, e.g. for offset and sensitivity, are stored in an internal EEPROM. The sensor also features full self-test capability for all three axes. It is activated via a single self test activation pin which results in a physical deflection of the seismic mass in the sensing element due to electrostatic forces. Thus, it provides contact and functional testing of the complete signal evaluation path including the MEMS acceleration-sensing element and the evaluation ASIC. 04 April 2008 Bosch Sensortec GmbH reserves all rights even in the event of industrial property rights.
