Combined Gyroscope and 3-Axis Accelerometer Data Sheet ADXC1501 FEATURES GENERAL DESCRIPTION Combined gyroscope and 3-axis, low g accelerometer
The ADXC1501 is a yaw rate gyroscope and 3-axis accelerometer
Temperature compensated, high precision bias, and
combined in a single package. It is designed for electronic
sensitivity performance
stability control and other high performance applications that
