Positive supply voltage (VDD)

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 floating or connected to GND.

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.
