Selectable ranges for analog output
FS voltage is not selectable – only 1 V FS is provided.
The analog output is driven by a 16-bit converter with an output range of 0–1 V FS with
+11%/-20% over-range. This gives an analog output resolution (at 1 AU/Volt)
= 1V*131% / 65535 = 20 uV= 20 uAU.
The Full Scale ranges are:
