KXTF9 Series
Accelerometers and Inclinometers
PERFORMANCE SPECIFICATIONS
The performance parameters below are programmed and tested at 1.8 volts (KXTF9-4100) and 3.3V (KXTF9-
2050). However, the devices can be factory programmed to accept supply voltages from 1.8V to 3.6V. Perfor-
mance parameters will change with supply voltage variations.
