"This is the first three-axis motion sensor accelerometer
and the first single-chip three-axis MEMS accelerometer with signal conditioning and circuitry together on the same chip," said Mack Lund, the company's product marketing manager for micromachined products. The chip's mechanical sensing structures allow it to offer low power in a small package while also providing stable performance over its temperature range, he said.
In addition, the device's low supply voltage, from 2.0 to 3.6V, benefits battery-powered applications, Lund said. "If users only need to use this for short periods of time or they want to duty-cycle it, they can get even lower power than best-in-class," he said. The device can turn on in 1 msec, take a measurement, and turn off again to save power, he said.

The ADXL330 is now sampling and costs less than $2 in high volume, according to the company. It is slated for volume production during the first quarter of next year.
