GSXV7021 Digital Quartz MEMS Gyro Chip
GSXV7021 brings gyro capability to chip-scale integration. The 8.9×8.9×2.7mm package consumes as little as 4mW (0.9mA) with SPI/I2C dual interface and 16/24-bit angular rate output. Bias temperature drift only 0.0016°/s/°C with angular random walk 0.065°/√h. Built-in programmable digital filters and temperature sensor. From wearables and medical motion detection to industrial image stabilization—chip-level gyro sensing empowers everything.

Product Introduction
The GSXV7021 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.
