Unipolar Configuration
Figure 2a shows the MAX5141
–
MAX5144 configured for
unipolar operation with an external op amp. The op amp
is set for unity gain, and Table 1 lists the codes for this
circuit. Bipolar MAX5142/MAX5144 can also be used in
unipolar configuration by connecting RFB and INV to
REF. This allows the DAC to power up to midscale.
Bipolar Configuration
Figure 2b shows the MAX5141
–
MAX5144 configured
for bipolar operation with an external op amp. The op
amp is set for unity gain with an offset of -1/2V
REF
.
Table 2 shows the offset binary codes for this circuit
(less than 0.25 inches).
Power-Supply Bypassing and
Ground Management
Bypass V
DD
with a 0.1μF ceramic capacitor connected
between V
DD
and GND. Mount the capacitor with short
leads close to the device (less than 0.25 inches).
