Description
CJMCU-941 is a tri-axis silicon micromachined accelerometer with a user selectable full-scale output range of ±2g, ±4g, ±6g or ±8g.
The sense element is fabricated using Kionix’s proprietary plasma micromachining process technology.
Acceleration sensing is based on the principle of a differential capacitance arising from acceleration-induced motion of the sense element,
which further utilizes common mode cancellation to decrease errors from process variation, temperature, and environmental stress.
The sense element is hermetically sealed at the wafer level by bonding a second silicon lid wafer to the device using a glass frit.
A separate ASIC device packaged with the sense element provides signal conditioning, self-test, and temperature compensation.
The accelerometer is delivered in a 3 x 3 x 0.9 mm LGA plastic package
operating from a 1.8 – 3.6V DC supply.
Either I2C or SPI interfaces can be used to communicate to the chip to trigger A/D conversions or manage power consumption.
