Description
The I3G4250D is a low-power 3-axis angular rate
sensor able to provide unprecedented stability at
zero-rate level and sensitivity over temperature
and time. It includes a sensing element and an IC
interface capable of providing the measured
angular rate to the application through a standard
SPI digital interface. An I2C compatible interface
is also available.
The sensing element is manufactured using a
dedicated micromachining process developed by
STMicroelectronics to produce inertial sensors
and actuators on silicon wafers.
The IC interface is manufactured using a CMOS
process that allows a high level of integration to
design a dedicated circuit which is trimmed to
better match the characteristics of the sensing
element.
The I3G4250D has a selectable full scale
(±245/±500/±2000 dps) and is capable of
measuring rates with a user-selectable
bandwidth.
The I3G4250D is available in a plastic land grid
array (LGA) package and can operate within a
temperature range of -40 °C to +85 °C.

1. Minimum and maximum values are not guaranteed; based on characterization data.
2. Typical specifications are not guaranteed; typical values at +25 °C.
3. It is possible to remove Vdd maintaining Vdd_IO without blocking the communication busses, in this condition the
measurement chain is powered off.
4. Sleep mode introduces a faster turn-on time compared to power-down mode.
5. Verified at wafer level.
