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. Measurement ranges of ±2 g, ±4 g, and ±8 g are available, with a resolution of 0.25 mg/LSB on the ±2 g range.

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.

EVAL-ADXL367Z

ADXL367 Breakout Board

Product Detail

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.

ADXL367 Customer Evaluation System

Product Detail

The EVAL-ADXL367-SDP is an easy-to-use Customer Evaluation System that allows the user a quick start on testing and evaluating the ADXL367 accelerometer. The system consists of a main board (EVAL-SDP-CB1Z evaluation platform), an interface board (EVAL-SDP-INTER4-Z), and a satellite board (EVAL-ADXL367Z breakout board). 

The EVAL-SDP-CB1Z board, also called “SDP-B”, connects directly to a PC via an USB cable, with the USB connection providing both communications and power to the board. The SDP-B is connected to the interface board (EVAL-SDP-INTER4-Z), which provides the signal conditioning and electrical connections to communicate with the satellite board (EVAL-ADXL367Z) through a 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 EVAL-ADXL367-SDP Customer Evaluation System comes with all the necessary cables and connectors. Each part of this kit can be purchased separately.
