Custom signal conditioning can be inserted between
DAC_VOUT and CONV_IN, or CONV_IN can be driven
independently by a voltage source if desired. See

CONV_IN.
Current Offset
Set EN_I high for a current span of 4–20mA. Set EN_I
low for a current span of 0 to 16mA. See Table 5 for
current output.
Unipolar Mode
Set EN_BPM low to engage unipolar operation. In unipo-
lar mode, the current output at 4-20OUT (4–20mA or 0 to
16mA) maps the analog input voltage (0 to 2V or 0 to
200mV). Negative voltages at the analog input result in a
4mA or 0mA output, depending on the EN_I setting. See
Table 5 for current output. See Figures 21 and 22.
Bipolar Mode
Set EN_BPM high to engage bipolar operation. In bipo-
lar mode, the current output at 4-20OUT (4–20mA or 0
to 16mA) maps the analog input voltage (±2V or
±200mV). In bipolar mode, a 0V analog input maps to
midscale (12mA). See Table 5 for current output. Also
see Figures 21 and 22 .
