RT3000A/B/C
3-Axis Digital Accelerometer
General Description
Features
The RT3000 is a low power and high accuracy 3 axis
acceleration sensor with digital output for portable device.
The part has user selectable full scales rages of ±2g, ±4g,
±8g and ±16g, and, it is capable of measuring accelerations
with output data rates from 1Hz to 200Hz. The RT3000A
is available in MQFN-16L 3x3, RT3000B in MQFN-12L
2x2 (COL) and RT3000C in MDFN-10L 3x3 package.
