= 12V or 15V unless otherwise noted.
NOTES: (1) Refer to “Logic Input Compatibility” section. (2) Adjustable to zero with external trim potentiometer. (3) FSR means full scale range and is 20V for
±
10V range,
10V for
±
5V range for V
models; 2mA for I
models. (4) To maintain drift spec, internal feedback resistors must be used. (5) Includes the effects of gain, offset
and linearity drift. Gain and offset errors externally adjusted to zero at +25
°
C. (6) For
±
V
less than
±
12VDC, limit output current load to
±
2.5mA to maintain
±
10V full
scale output voltage swing. For output range of
±
5V or less, the output current is
±
5mA over entire
±
V
CC
range. (7) Short circuit current is 40mA, max.
