Note 3: The maximum load that the analog output can drive is calculated by dividing the full-scale output
voltage by the current output specification or (10 V/10 mA) = 1000 Ω. This calculation is valid
whether the Remote Sense feature is enabled or disabled.
Note 4: The USB-1608HS-2AO Remote Sense feature can compensate for any series resistance up to
75 Ω between its force terminal pins and its output load.
Note 5: R
load
should not exceed the specified 1000 Ω, and the R
series
should not exceed its specified limit
of 75 Ω.
