Self test can be activated applying logic “1” (positive supply voltage level)
to ST pin (pin 9 and 10). If ST feature is not used pins 9 and 10 must be
left fl oating or connected to GND.
INTERCHANGEABILITY WITH SCA610 / SCA620
When SCA1000 / 1020 is used in Analog mode and the PCB is designed correctly the
SCA610 / 620 and SCA1000 / 1020 are interchangeable. If the PCB layout is designed
for SCA1000 /1020, then SCA610 / 620 can be used for single axis applications. The
output of SCA610 / 620 corresponds to the output of channel 1 in the SCA1000 / 1020.
