Anglia stocking ultra-low-power MEMS accelerometer

This is said to be the lowest power consumption currently available on the market.

It is in stock at distributor Anglia Components.

Unlike accelerometers that use power duty cycling to achieve low power consumption, the accelerometer does not alias input signals by undersampling, but samples the full bandwidth of the sensor at all data rates.

In addition to ultralow power consumption, the device has many additional features to enable true system-level power reduction.

These include a deep multimode output first in, first out (FIFO), a built-in micropower temperature sensor, an internal analogue-to-digital converter (ADC) for synchronous conversion of an additional analogue 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 device has provisions for external control of the sampling time and/or an external clock.

The ADXL367 always provides 14-bit output resolution with 8-bit formatted data offered for more efficient single-byte transfers when a lower output resolution is sufficient. 12-bit formatted data is also provided allowing for design compatibility with the ADXL362 MEMS sensor from Analog Devices.

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.

The accelerometer 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.

It has internal voltage regulation and the capability to operate from a 1.1V supply means it can operate directly connected to battery cells including zinc air batteries.

The device is housed in a compact LGA package measuring just 2.2 mm × 2.3 mm × 0.87 mm, and has an industrial temperature range of -40°C to +85°C.

The ADXL367 is supported by the EVAL-ADXL367-SDP, an easy-to-use Customer Evaluation System that allows the user a quick start on testing and evaluating the 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).
