KXTJ9-1007 ± 2g / 4g / 8g Tri-axis Digital Accelerometer Specifications

2020-04-26
The KXTJ9 is a tri-axis +/-2g, +/-4g or +/-8g silicon

micromachined accelerometer. 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 and digital

communications. 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. Voltage regulators are used to maintain

constant internal operating voltages over the range of

input supply voltages. This results in stable operating

characteristics over the range of input supply voltages and virtually undetectable ratiometric error.

The I

2C digital protocol is used to communicate with the chip to configure the part and monitor

outputs.
