The QMI8660 is a complete 6D MEMS inertial measurement unit. With tight board-level gyroscope sensitivity of ±1%, gyroscope noise density of 8 mdps/√Hz, and low latency, the QMI8660 is ideal for consumer applications.
The QMI8660 incorporates a 3-axis gyroscope and a 3-axis accelerometer. It provides a host-processor interface supporting I³C, I²C and 3-wire or 4-wire SPI, and the 3-wire or 4-wire OIS interface to communicate to second host.
With its built-in digital functionality, low power, and small size, the QMI8660 is the ideal part for applications requiring motion-based functionality.
▪ Low 8 mdps/√Hz gyroscope noise density, low-latency, and wide bandwidth
