Keithley DAC-02 User Manual page 17

The DAC-02 board consists of two separate, double-buffered, 12-bit,
multiplying DACs (digital-to-analog converters) and interface circuitry.
The DACs can operate as conventional D/A (digital-to-analog) converters
if they are used with a fixed DC reference. Using the DACs with the
onboard fixed DC references of
follows:
0 to 10 V
0 to 5 V
±5 V
±10 V
4 to 20 mA current loop (sink)
Alternatively, the DACs can operate as multiplying D/A converters if they
are used with a variable or AC reference. As multiplying D/A conveters,
the DAC outputs are the product of reference and digital inputs. With an
AC reference, the unipolar outputs provide 2-quadrant multiplication, or
the bipolar outputs provide 4-quadrant operation. With an AC reference,
the DACs also maintain 12-bit accuracy up to 1 kHz.
