4-Quadrant Multiplic ation
Each DAC output may be configured for 4-quadrant
multiplication using Figure 16 and 17's circuit. One op
amp and two resistors are required per channel. With
R1 = R2:
V
OUT
= V
REF
[2(NB/256)-1]
where NB represents the digital word in DAC register A.
The recommended value for resistors R1 and R2 is
330k
(±0.1%). Table 3 shows the digital code vs. out-
put voltage for Figure 16 and 17's circuit.
