MAX21003 Ultra-Accurate, Low Power, Dual-Axis Digital Output Gyroscope

Maxim provides the industry's smallest footprint package (3 mm x 3 mm LGA16) and a low power supply (1.8 V) gyroscope

The MAX21003 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 1.71 V 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 large BW, low noise at highest FS, together with low phase delay make the IC suitable for optical image stabilization (OIS) applications.

The IC is a highly-integrated solution available in a compact 3 mm x 3 mm x 0.9 mm 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.
