Application Design Equations
1. The bandwidth is determined by the internal 1kHz low pass filter. The user can lower the bandwidth
by placing filter capacitors connected from pins 2, 13 and 14 to ground. The response is single pole.
Given a desired bandwidth, f_BW, the filter capacitors are determined by:

2. When using not using the multiplexer, the KXR94 is a pin-compatible replacement for Kionix’s
KXM52 series of accelerometers. The following application schematic should be used:
Pin 4 (Aux in) = Ground
Pin 5 (Vmux) = Do Not Connect
Pin 6 (S0) = Ground
Pin 7 (S1) = Ground

3. When not connecting the self test pin to a digital I/O port of a microcontroller, Kionix recommends
connecting the self test pin to ground.
