KSGYR111M-S Digital Quartz MEMS GYRO Chip
Product Introduction
The KSGYR111M-S feature superior bias output stability and low noise. Digital quartz gyroscope is based on quartz MEMS technology and completed by semiconductor processing technology.
In addition to compatibility for digital output interfaces (SPI, I2C), these sensors allow for independent interface power supply voltage settings to enable communications with various interfaces. User-selectable low-pass filters and high-pass filters enable a wide range of cut-off frequencies. Designed for low power consumption, these sensors are suitable for a wide range of uses, from wearable devices and other consumer electronics to industrial equipment.
