KX122-1037 ± 2g / 4g / 8g Tri-axis Digital Accelerometer Specifications
accelerometer with integrated 2048-byte buffer, orientation,
Directional-TapTM/Double-TapTM, activity detecting, and Free fall
algorithms. 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 intelligent user-programmable application algorithms. The accelerometer is
delivered in a 2 x 2 x 0.9 mm LGA plastic package operating from a 1.71V – 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. I
2C or
SPI digital protocol is used to communicate with the chip to configure and check for updates to the
orientation, Directional-TapTM/Double-TapTM detection, Free fall detection, and activity monitoring
algorithms.
