Overview: Document #: 13-52-12 Title: QMA7981 Datasheet 矽睿 Rev: D Abstract Single-Chip 3-Axis Accelerometer QMA7981 Advanced Information The QMA7981 is a single chip three-axis accelerometer. This surface-mount, small sized chip has integrated acceleration transducer with signal conditioning ASIC, sensing tilt, motion, shock and vibration, targeted for applications such as screen rotation, step counting, sleep quality, gaming and personal navigation in mobile and wearable smart devices.
The QMA7981 is based on our state-of-the-art, high resolution single crystal silicon MEMS technology. Along with custom-designed 14-bit ADC ASIC, it offers the advantages of low noise, high accuracy, low power consumption, and offset trimming. The device supports digital interface IIC and SPI.
The QMA7981 is in a 2x2x0.95mm3 surface mount 12-pin land grid array (LGA) package.
