USER GUIDE

SCC-ACC01 Accelerometer Input 
Module

The SCC-ACC01 accelerometer (ACC) input module accepts an active 
accelerometer input signal, passes it through a 0.8 Hz highpass filter, 
amplifies it, and then passes it through a 19 kHz lowpass Bessel filter and 
an output buffer. The module has a fixed gain of 2, so the maximum input 
range is 

±

5 V. The SCC-ACC01 also provides a 4 mA current source for 

accelerometer excitation.

Conventions

The following conventions are used in this guide:

Angle brackets that contain numbers separated by an ellipsis represent 
a range of values associated with a bit or signal name—for example, 
P0.<3..0>.
