Notes (Power):
1. The ±12 volt power supplies are normally supplied through P1
(logic interface connector). Optionally (jumper selectable on the
IP), the user may connect external ±15 volt supplies through the
field I/O interface connector, P2.
2. The maximum current draw assumes that the rated current of
5mA per channel is drawn. Current draw will be reduced
proportionately for high impedance output loads.

Notes (Analog Outputs):
3. Maximum output current (±5mA) can be achieved at the range
endpoints using the internal ±12 volt power supplies sourced
through P1. The external ±15 volt power supplies, sourced
through P2, are not required to achieve rated output.
4. The actual outputs may fall short of the range endpoints due to
hardware offset and gain errors. The software calibration
corrects for these across the output range, but cannot extend
the output beyond that achievable with the hardware.
5. Offset and gain calibration coefficients stored in the ID PROM
must be used to perform software calibration in order to achieve
the specified accuracy. Specified accuracy does not include
quantization error. Follow the output connection
recommendations of Section 2, because non-ideal grounds can
degrade overall system accuracy.
6. The reset function resets only the D/A (i.e. output) latch of the
input double buffer. Therefore, after a reset, good data must be
written to all the input latches before a simultaneous DAC output
update. Otherwise, old data or unknown data present in the
input latches will be transferred to the D/A output latch,
producing an undesired analog output.
