It's a nice part. We're using the 10 amp version at up to 7.5 amps.
The 50 amp version is silly.

Well, when you actually get around to using it (probably in a

data lines. R in series with source, C at receiving end.

That Monolithic Hall sensor is analog output. Zero current outputs
Vcc/2, and the sensitivity is ratiometric on Vcc. So one uses the same
rail for sensor Vcc and for the ADC reference. We'll autozero it every
powerup.

I'll RC filter a bit, right at the ADC input. Most ADCs kick out some

I'll have eight Hall sensors on a board, about like this one:

No, surface-mount, on the board. Close to the ADCs.

Connector pins carry 8x 10A load current?
