Figure 25. Bipolar Configuration (Four-Quadrant Multiplication)
resistors R5, R6, R7, should be ratio-matched to 0.01% so that
gain error meets data sheet specifications. (Corresponding resis-
tors, R8, R9, and R10 for DAC B should also be matched to
0.01%). The resistors should have identical temperature coeffi-
cients if operating over the full temperature range.
Zero and full-scale are adjusted one of two ways and are at the
user’s discretion. Zero-output can be adjusted by first setting
the digital inputs to 1000 0000 0000 and adjusting R1 (R3 for
DAC B) so that V
OUTA
(or V
OUT B
) equals 0 V. If R1, R2 (R3,
R4 for DAC B) are omitted, then V
OUT
= 0 V can be adjusted
by varying R6, R7 (R9, R10 for DAC B) ratios. Full-scale is ad-
justed by setting the digital inputs to 1111 1111 1111 and vary-
ing R5 (R8 for DAC B). Full-scale can also be adjusted by
varying V
REF
. Full-scale output is equal to V
REF
minus one LSB.
