Output Range:
Can be configured for one of seven nominal output ranges shown
below. All output ranges include approximately 5% under/over-range capability.

–5V to +5V
–5.25V to +5.25V
0 to +10V
–0.5527V to +10.5V
0 to +5V
–0.27634V to +5.25V
±20mA

–1.1054mA to +21mA
Output Resolution:
Output is driven by a
16-bit Voltage DAC, Maxim
MAX, with a 2.5V reference, and driving a universal current/voltage
output driver. The output resolution per output range is indicated below. The
effective I/O resolution of the transmitter will be the lowest resolution of the input,
and the output DAC relative to the programmed I/O ranges.

Output Load:
Voltage output can dr
ive loads down to 1000Ω minimum.
Current
output can drive ±21mA DC into 525
Ω
maximum.
Note (High Speed Acquisition):
Additional filtering at the load is recommended for
sensitive applications with high-speed acquisition rates. High frequency noise is
often reduced or eliminated by placing a 0.1uF capacitor directly across the load. For
excessive 60Hz supply ripple with current output, a 1uF or larger bulk capacitor is
recommended at the load.
Output Load Resistance Effect:
Less than
±
0.005% of output span effect per
±
100
Ω
change in load resistance.
Output Ripple:
Less than
±
0.1% of output span.
Output Ambient Temperature Drift:
Includes the combined effects of zero and span
drift over temperature and is typically better than
±
40ppm/
°
C (±0.0040%/
°
C) over
the ambient temperature range for reference test conditions (see Input
Specifications).
