ADXL362Micropower, 3-Axis, ±2g/±4g/±8gDigital Output MEMS Accelerometer | Sensor Evaluation Boards | 6 | Active | 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 ±2g, ±4g, and ±8gare available, with a resolution of 1 mg/LSB on the ±2grange. 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.APPLICATIONSHearing aidsHome healthcare devicesMotion enabled power save switchesWireless sensorsMotion enabled metering devices |

ADXL367Nanopower, 3-Axis, ±2g/±4g/±8gDigital Output MEMS Accelerometer | Evaluation Boards | 2 | Active | The ADXL367 is an ultralow power, 3-axis microelectromechanical systems (MEMS) accelerometer that consumes only 0.89 μA at a 100 Hz output data rate and 180 nA when in motion-triggered wake-up mode. Unlike accelerometers that use power duty cycling to achieve low power consumption, the ADXL367 does not alias input signals by undersampling, but samples the full bandwidth of the sensor at all data rates.The ADXL367 always provides 14-bit output resolution. 8-bit formatted data is offered for more efficient single-byte transfers when a lower resolution is sufficient. 12-bit formatted data is also provided for ADXL362 design compatibility. Notice that the low and high bytes are inverted, compared with the ADXL362 word formatting. Measurement ranges of ±2g, ±4g, and ±8gare available, with a resolution of 0.25 mg/LSB on the ±2grange.In addition to its ultralow power consumption, the ADXL367 has many features to enable true system level power reduction. It includes a deep multimode output first in, first out (FIFO), a built-in micropower temperature sensor, an internal analog-to-digital converter (ADC) for synchronous conversion of an additional analog input with interrupt capability, single-tap and double-tap detection that can operate at any output data rate with only an added 35 nA of current, and a state machine to prevent a false triggering. In addition, the ADXL367 has provisions for external control of the sampling time and/or an external clock.The ADXL367 operates on a wide 1.1 V to 3.6 V supply range, and can interface, if necessary, to a host operating on a separate supply voltage. The ADXL367 is available in a 2.2 mm × 2.3 mm × 0.87 mm package.APPLICATIONS24/7 sensingHearing aidsVital signs monitoring devicesMotion-enabled power save switchesMotion-enabled metering devicesSmart watch with single-cell operationSmart home |
ADXL371Micropower, 3-Axis, ±200gDigital Output, MEMS Accelerometer | Accelerometers | 2 | Active | The ADXL371 is an ultra low power, 3-axis, ±200gmicroelectromechanical system (MEMS) accelerometer that consumes 28 μA at a 2560 Hz output data rate (ODR). The ADXL371 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 ADXL371 enables impact detection while providing system level power reduction. The device includes a deep multimode output first in, first out (FIFO), several activity detection modes, and a method for capturing only the peak acceleration of overthreshold events.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 lowgthresholds. In instant on mode, the ADXL371 consumes 1.7 μA 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.Highgapplications tend to experience acceleration content over a wide range of frequencies. The ADXL371 includes a four-pole, low-pass antialiasing filter to attenuate out of band signals that are common in highgapplications. The ADXL371 also incorporates a high-pass filter to eliminate initial and slow changing errors, such as ambient temperature drift.The ADXL371 provides 12-bit output data at a 100 mg/LSB scale factor. The user can access configuration and data registers via the serial peripheral interface (SPI) or I2C protocol. The ADXL371 operates over a wide supply voltage range and is available in a 3 mm × 3.25 mm × 1.06 mm package.APPLICATIONSImpact and shock detectionAsset health assessmentPortable Internet of Things (IoT) edge nodesConcussion and head trauma detection |
