2.1.1 Recommended connection when SPI interface is used

2.1.2 Recommended connection when analog output is used

When SCA1020 is used in Analog mode and the PCB is designed correctly the SCA610 / 620 and

SCA1020 are interchangeable. If the PCB layout is designed for SCA1020, then SCA610 / 620 can

be used for single axis applications. Pins 1, 2, 3, 4 and 8 can be connected to GND (pins 2 and 8

can be connected also to Vdd) but for the best EMC performance these pins should be left floating.

CSB pin can be pulled up but it is recommended to left floating. The output of SCA610 / 620

corresponds to the output of channel 1 in the SCA1020
