Description

The A3G4250D 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 external world through a

standard SPI digital interface. An I2C-compatible

interface is also available.

The sensing element is manufactured using a

dedicated micro-machining 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 sensing element characteristics.

The A3G4250D has a full scale of ±245 dps and

is capable of measuring rates with a user-

selectable bandwidth.

The A3G4250D is available in a plastic land grid

array (LGA) package and can operate within a

temperature range of -40 °C to +85 °C.
