b) Output span voltage adjustment (Register names: SCS, SC)
Adjusts the span voltage.
The magnification factor in this table represents an adjustment factor benchmarked to a VOUT output of
4000mV (@VDD: 5V) as 1 (factor) = 100[%]/100[%].
The output and sensitivity describes the adjustable output voltages with the assumed reference
output (2V@VDD: 3V, 4V@VDD: 5V) when ESC[8:0] = 0 dec.
