The MAX21003 is a low power, low noise, dual-axis angu-
lar 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 (I
2
C/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 com-
pact 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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
Drops onto hard surfaces can cause shocks of greater than 10,000 g and can exceed the absolute maximum rating of the device. Exercise care in handling to avoid damage.

Note 3:
In standby mode, only the drive circuit is powered on. In this condition, the outputs are not available. In this condition, the
startup time depends only on the filters responses.
Note 4:
In eco mode, the sensor has higher rate noise density, but lower current consumption. In this condition, the selectable out-
put data rate (ODR) is either 25Hz, 50Hz, 100Hz, or 200Hz.
