GENERAL DESCRIPTION
The ADIS16003 is a low cost, low power, complete dual-axis
accelerometer with an integrated serial peripheral interface
(SPI). An integrated temperature sensor is also available on the
SPI interface. The ADIS16003 measures acceleration with a full-
scale range of 卤1.7
g
(minimum), and it can measure both
dynamic acceleration (vibration) and static acceleration
(gravity).
The typical noise floor is 110 渭g/鈭欻z, allowing signals below
1 mg (60 Hz bandwidth) to be resolved.
The bandwidth of the accelerometer is set with optional capaci-
tors C
X
and C
Y
at the XFILT and YFILT pins. Selection of the
two analog input channels is controlled via the serial interface.
An externally driven self-test pin (ST) allows the user to verify
the accelerometer functionality.
The ADIS16003 is available in a 7.2 mm 脳 7.2 mm 脳 3.6 mm,
12-terminal LGA package.
