Unipolar Configuration
Figure 2a shows the MAX5441–MAX5444 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. The bipolar MAX5442/MAX5444 can also be
used in unipolar configuration by connecting RFB and
INV to REF. This allows the DAC to power-up to mid-
scale.
Bipolar Configuration
Figure 2b shows the MAX5442/MAX5444 configured for
bipolar operation with an external op amp. The op amp
is set for unity gain with an offset of -1/2VREF. Table 2
lists the offset binary codes for this circuit.
Power-Supply Bypassing and
Ground Management
Bypass VDD with a 0.1F ceramic capacitor connected
between VDD and GND. Mount the capacitor with short
leads close to the device (less than 0.25 inches).
