Summary of MAX21002 – Ultra-Accurate, Low Power, Dual-Axis Digital Output Gyroscope
The MAX21002 is a compact, low-power dual-axis gyroscope designed for high-precision applications like optical image stabilization. It features an integrated sensing element and digital interface (I2C/SPI), eliminating the need for external components. With ultra-low noise, wide bandwidth, and extensive programmability, it operates efficiently across a broad temperature range while maintaining exceptional accuracy and stability over time.
Parts used in the MAX21002 Gyroscope Project:
- Dual-axis angular rate sensor
- Sensing element
- IC interface
- Digital interface (I2C/SPI)
- Embedded digital-output temperature sensor
- Digitally programmable filters
- Flexible embedded FIFO
- Flexible interrupt generator
- Data synchronization pin
- 48-bit serial number as Die ID
The MAX21002 is a low-power, low-noise, dual-axis angular rate sensor that delivers unprecedented accuracy and sensitivity over temperature and time.
It operates with a supply voltage as low as 1.71V for minimum power consumption. It includes a sensing element and an IC interface that provides the measured angular rate to the external world through a digital interface (I2C/SPI).
The IC has a full scale of ±31.25/±62.50/±125/±250/ ±500/±1000 degrees per second (dps) and measures rates with a finely tunable user-selectable bandwidth. The high ODR and the large BW, the low noise at highest FS, together with the low phase delay, make the IC suitable for optical image stabilization (OIS) applications.
The IC is a highly integrated solution available in a compact 3mm x 3mm x 0.9mm plastic land grid array (LGA) package and does not require any external components other than supply bypass capacitors. It can operate over the -40°C to +85°C temperature range.
