The ADXL362 is an ultralow power, 3-axis MEMS accelerometer that consumes less than 2 ?A 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 ?g/?Hz of the ADXL362 is desired, either of two lower noise modes (down to 175 ?g/?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 ADXL213 is a low cost, low power, complete dual axis accelerometer with signal conditioned, duty cycle modulated outputs, all on a single monolithic IC. The ADXL213 measures acceleration with a full-scale range of ?1.2 g (typical). The ADXL213 can measure both dynamic acceleration (e.g., vibration) and static acceleration (e.g., gravity).The outputs are digital signals whose duty cycles (ratio of pulse width to period) are proportional to acceleration (30%/g). The duty cycle outputs can be directly measured by a microcontroller without an A/D converter or glue logic.Innovative design techniques are used to ensure high zero g bias stability (typically better than 0.25 mg/?C), as well as tight sensitivity stability (typically better than 50 ppm/?C).The typical noise floor is 160 ?g/?, allowing signals below 1 mg (0.06? of inclination) to be resolved in tilt sensing applications using narrow bandwidths (The user selects the bandwidth of the accelerometer usingcapacitors CX and CYM at the XFILT and YFILT pins. Bandwidths of0.5 Hz to 250 Hz may be selected to suit the application.The ADXL213 is available in a 5mm x 5mm x 2mm, 8-pad hermetic LCC package.ApplicationsAutomotive tilt alarmData projectorsNavigationPlatform stabilization/levelingAlarms and motion detectorsHigh accuracy, 2-axis tilt sensing

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 EVAL-ADXL367Z is a simple breakout board that enables easy connection of an ADXL367 into an existing system. The ADXL367 is a nanowatt, 3-axis, digital-output accelerometer whose industry leading low power consumption and built-in features make it ideal for use in a wide variety of applications. Due to its small size, the EVAL-ADXL367Z has minimal effect on performance of the system and of the accelerometer, and thus it is ideal for evaluation of the ADXL367 in an existing system. Note that the ADXL367 must be communicated with digitally via SPI or I2C. No processor is included with the EVAL-ADXL367Z; firmware must be supplied externally by the user. For evaluation boards that include a processor, please see the EVAL-ADXL367-SDP. MARKETS & TECHNOLOGY Industrial Digital Healthcare Prosumer Automotive Aerospace and Defense
