reference, the DAC output will provide a proportional dc voltage
output according to the transfer equation:
VOUT = –D/4096
× VREF
where D is the decimal data loaded into the DAC register and
VREF is the externally applied reference voltage source.

BIPOLAR 4-QUADRANT MULTIPLYING
Figure 20 shows a suggested circuit to achieve 4-quadrant mul-
tiplying operation. The summing amplifier multiplies VOUT1 by
2, and offsets the output with the reference voltage so that a
midscale digital input code of 2048 places VOUT2 at zero volts.
The negative full-scale voltage will be VREF when the DAC is
loaded with all zeros. The positive full-scale output will be
–(VREF – 1 LSB) when the DAC is loaded with all ones. Thus
the digital coding is offset binary. The voltage output transfer
equation for various input data and reference (or signal) values
follows:
VOUT2 = (D/2048 – 1)
× –V
REF
where D is the decimal data loaded into the DAC register and
VREF is the externally applied reference voltage source.
Precision resistors will be necessary to avoid ratio errors. Other-
wise trimming will be required to achieve full accuracy specifica-
tions available from the DAC8043A device. See the various
Analog Devices Digital Potentiometer products for automated
trimming solutions (e.g., the AD5204 for low voltage applica-
tions or the AD7376 for high voltage applications).
