The ADXL362 is an ultralow power, 3-axis MEMS accelerometer that consumes less than 2 μA at a 100 Hz output data rate and 270 nA when in motion triggered wake-up mode. Unlike accelerometers that use power duty cycling to achieve low power consumption, the ADXL362 does not alias input signals by undersampling; it samples the full bandwidth of the sensor at all data rates.The ADXL362 always provides 12-bit output resolution; 8-bit formatted data is also provided for more efficient single-byte transfers when a lower resolution is sufficient. Measurement ranges of ±2 g, ±4 g, and ±8 g are available, with a resolution of 1 mg/LSB on the ±2 g range. For applications where a noise level lower than the normal 550 μg/√Hz of the ADXL362 is desired, either of two lower noise modes (down to 175 μg/√Hz typical) can be selected at minimal increase in supply current.In addition to its ultralow power consumption, the ADXL362 has many features to enable true system level power reduction. It includes a deep multimode output FIFO, a built-in micropower temperature sensor, and several activity detection modes including adjustable threshold sleep and wake-up operation that can run as low as 270 nA at a 6 Hz (approximate) measurement rate. A pin output is provided to directly control an external switch when activity is detected, if desired. In addition, the ADXL362 has provisions for external control of sampling time and/or an external clock.The ADXL362 operates on a wide 1.6 V to 3.5 V supply range, and can interface, if necessary, to a host operating on a separate, lower supply voltage. The ADXL362 is available in a 3 mm × 3.25 mm × 1.06 mm package.APPLICATIONS Hearing aids Home healthcare devices Motion enabled power save switches Wireless sensors Motion enabled metering devices

The ADXL313 is a small, thin, low power, 3-axis accelerometer with high resolution (13-bit) measurement up to ?4g. Digital output data is formatted as 16-bit twos complement and is accessible through either a serial port interface (SPI) (3-wire or 4-wire) or I2C digital interface.The ADXL313 is well suited for car alarm or black box applications. It measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (1024 LSB/g) and low noise (150 ?g/?Hz) enable resolution of inclination changes of as little as 0.1?. A built-in FIFO facilitates using oversampling techniques to improve resolution to as little as 0.025? of inclination.Several built-in sensing functions are provided. Activity and inactivity sensing detects the presence or absence of motion and whether the acceleration on any axis exceeds a user-set level. These functions can be mapped to interrupt output pins. An integrated 32-level FIFO can be used to store data to minimize host processor intervention, resulting in reduced system power consumption.Low power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement at extremely low power dissipation.The ADXL313 is supplied in a small, thin 5 mm ? 5 mm ? 1.45 mm, 32-lead LFCSP package and is pin compatible with the ADXL312 accelerometer device.APPLICATIONS Car alarms Hill start aid (HSA) systems Electronic parking brakes Data recorders (black boxes)

The ADXL355 multifunction pin names may be referenced by their relevant function only for either the serial peripheral interface (SPI) or I2C interface.Applications Inertial measurement units (IMUs)/altitude and heading reference systems (AHRS) Platform stabilization systems Structural health monitoring Seismic imaging Tilt sensing Robotics Condition Monitoring

The ADXL363 is an ultralow power, three-sensor combination consisting of a 3-axis MEMS accelerometer, a temperature sensor, and an on-board analog-to-digital converter (ADC) input for synchronous conversion of an external signal. The entire system consumes less than 2 ?A at a 100 Hz output data rate and 270 nA when in motion triggered wake-up mode.The ADXL363 communicates via a serial port interface (SPI) and always provides 12-bit output resolution for all three sensors.The ADXL363 temperature sensor operates with a scale factor of 0.065?C/LSB (typical). Acceleration and temperature data can be stored in a 512-sample multimode first in, first out (FIFO) buffer, allowing up to 13 sec of data to be stored.In addition to the accelerometer and temperature sensor, the ADXL363 also provides access to an internal ADC for synchronous conversion of an additional analog input.The ADXL363 operates on a wide 1.6 V to 3.5 V supply range, and can interface, if necessary, to a host operating on a separate, lower supply voltage. The ADXL363 is available in a 3 mm ? 3.25 mm ? 1.06 mm package.APPLICATIONS Home healthcare devices Wireless sensors Motion enabled metering devices

The iMEMS® ADXL372 inertial sensor evaluation system is an easy-to-use evaluation tool targeting bench or desktop characterization of Analog Devices, Inc., inertial sensor products. The system consists of the inertial sensor evaluation board (ISEB), or main board, and a satellite board for any Analog Devices inertial sensor product. The ISEB connects directly to a PC via an USB cable, with the USB connection providing both communications and power to the board. The ISEB is connected to the satellite board through a ribbon cable. This cable allows the satellite to be easily manipulated for testing or separately placed into an environmental chamber for temperature or humidity testing. Separating the boards mitigates corruption of data due to the temperature and humidity effects of other components. The ISEB is an universal main board and is intended to be used with various satellites of Analog Devices inertial sensors, including analog and digital accelerometers, as well as gyroscopes. The different products are evaluated by means of separate GUIs that are customized for performance and characterization measurements relevant to the inertial sensor being evaluated. There are two kinds of mother board, one named –M and the other named –MLP. The difference between –M and –MLP is just the shunt resistor R13 and the gain resistor R17 which are used to detect the power consumption of the DUT (Device Under Test). EVAL-ADXL372-M used the –M mother board. As ADXL372 is pin-to-pin compatible with ADXL362, the ADXL362 satellite board can be reused for ADXL372. The EVAL-ADXL372Z-M system contains the ISEB and the EVAL-ADXL372Z-S satellite. Also included is an USB A to Mini-B cable to connect the ISEB to a PC and an 18-inch, 20-pin ribbon cable to connect the ISEB to the satellite.

The ADXL373 is an ultra low power, 3-axis, ?400 g microelectromechanical systems (MEMS) accelerometer that consumes 19 ?A at a 2560 Hz output data rate (ODR). The ADXL373 does not power cycle its front end to achieve its low power operation and therefore does not run the risk of aliasing the output of the sensor.In addition to its ultra low power consumption, the ADXL373 enables impact detection while providing system level power reduction.Two additional lower power modes with interrupt driven, wake-up features are available for monitoring motion during periods of inactivity. In wake-up mode, acceleration data can be averaged to obtain a low enough output noise to trigger on low g thresholds. In instant on mode, the ADXL373 consumes 1.4 ?A while continuously monitoring the environment for impacts. When an impact event that exceeds the internally set threshold is detected, the device switches to normal operating mode fast enough to record the event.High g applications tend to experience acceleration content over a wide range of frequencies. The ADXL373 includes a four-pole, low-pass antialiasing filter to attenuate out-of-band signals that are common in high g applications. The ADXL373 also incorporates a high-pass filter to eliminate initial and slow changing errors such as ambient temperature drift.The ADXL373 provides 12-bit output data at 200 mg/LSB scale factor. The user can access configuration and data registers via the serial peripheral interface (SPI) or I2C protocol. The ADXL373 operates over a wide supply voltage range and is available in a 3.00 mm ? 3.25 mm ? 1.06 mm package.
