Note:
The extended temperature grade version of the DAC714 is no longer
available from the manufacturer. Acromag has performed operational
tests of sampled commercial grade components over the extended
temperature range without failure. All DAC714s’ used on the -E
version of the PMC230 have been functionally tested by an
independent third party laboratory for use in extended temperature
applications, except for verification of analog output specifications.
Relative Humidity….....................5-95% Non-Condensing.
Storage Temperature.…............. -55

C.
Non-Isolated....................…...…. Logic and field commons have a
direct electrical connection.
Radiated Field Immunity (RFI).. Designed to comply with IEC1000-
4-3 Level 3 (10V/m, 80 to
1000MHz AM & 900MHz. keyed)
and European Norm EN50082-1
with error less than
±
0.25% of
FSR.
Electromagnetic Interference
Immunity (EMI)…...…..……......
Error is less than
±
0.25% of FSR
under the influence of EMI from
switching solenoids, commutator
motors, and drill motors.
Surge Immunity……………….… Not required for signal I/O per
European Norm EN50082-1.
ESD Protection……..........…....
Complies with IEC1000-2 Level 1
(2KV direct contact discharge at
input/output terminals) and
European Standard EN50082-1.
Electric Fast Transient
Immunity (EFT)……………..…..
Complies with IEC1000-4-4 Level
2 (0.5KV at field input and output
terminals) and European Norm
EN50082-1.
Radiated Emissions ………....... Meets or exceeds European Norm
EN50081-1 for class A equipment.
Warning: This is a class A product. In a domestic environment
this product may cause radio interference in which the
user may be required to take adequate measures.

ANALOG OUTPUTS
Output Channels (Field Access).. 8 Single Ended PMC230-8
Output Signal Type................…...Voltage (Non-isolated).
Output Ranges
1
............…………Bipolar -5 to +5 Volts
(Jumper selected): Bipolar -10 to +10 Volts
Unipolar 0 to +10 Volts
Note (Analog Outputs):
1. 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.
Output Current…………………...-5mA to +5mA (Maximum); this
corresponds to a minimum load
resistance of 2K
Ω
with a 10V
output.
DAC Data Format………………..Positive-true binary two’s
complement (BTC) input codes.
DAC Programming...................…Simultaneous; Input registers of
multiple DAC's are directly loaded
with new data before
simultaneously updating DAC
outputs.
Resolution..............................…..16-bits.
Monotonicity over Temperature…16-bits (PMC230)
15-bits (PMC230E).
Linearity Error...........................…+ 2 LSB (Maximum).

Notes (Calibrated Error):
2. Offset and gain calibration coefficients stored in the coefficient
memory must be used to perform software calibration in order to
achieve the specified accuracy. Specified accuracy does not
include quantization error and are with outputs unloaded. Follow
the output connection recommendations of Chapter 2, to keep a
non-ideal grounds from degrading overall system accuracy.
3. The maximum uncalibrated error combining the linearity, offset
and gain errors is
±
0.453%.
DAC714HL @ 25oC:
Linearity Error is
±
0.003% maximum (i.e.
±
2 LSB).
Bipolar Offset Error is
±
0.2% FSR (i.e. 20V SPAN) max.
Gain Error is
±
0.25% maximum.
Settling Time................................10uS to within 0.003% of FSR for
a 20V step change (load of 5K
Ω
in
parallel with 500pF).
Conversion Rate (per channel)....150KHz Maximum,
100KHz recommended for
specified accuracy.
Maximum Throughput……………8 X conversion rate (PMC230-8)

Output at Reset............................Bipolar Zero Volts.
Unipolar 5 Volts (See Note 4)
Board Warm-up Time...................8 minutes minimum
Note (Analog Output):
4. The reset function resets the DAC analog output and the FPGA’s
internal DAC registers. Therefore, the DAC output will remain in
their reset state after simultaneous DAC output updates until the
DAC registers are overwritten with new data.
Output Impedence........................0.1

Typical at 25oC
Short Circuit Protection ................Indefinite at 25oC.
