Product Description
The KXV9721 possesses exceptional attributes such as superior bias output stability and low noise level. The digital quartz gyroscope is primarily based on the innovative quartz MEMS technology, which is then enhanced by the application of semiconductor processing technology.
What's more, these sensors have the added advantage of being compatible with digital output interfaces like SPI and I2C. Additionally, they permit independent settings of interface power supply voltage. This attribute ensures seamless communication with different interfaces. The low-pass and high-pass filters, which are user-selectable, offer a vast range of cut-off frequencies.
The sensors are specially designed to consume minimal power while delivering optimum performance. As a result, they can be widely employed in various fields spanning wearable devices, consumer electronics, and industrial equipment, among others.
