Overview

± 2g / 4g / 8g / 16g Tri-axis Digital Accelerometer Specifications PART NUMBER: KXTJ3-1057 Rev.

0 23-Jun-2023 Product Description The KXTJ3-1057 is a tri-axis ±2g, ±4g, ±8g, or ±16g 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 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 and virtually undetectable ratiometric error.
The I2C digital protocol is used to communicate with the chip to configure the part and monitor outputs.
