__________Applications Information

Unipolar Output

Figure 9 depicts the MAX5152/MAX5153 configured for

unity-gain, unipolar operation. Table 2 lists the unipolar

output codes. To increase dynamic range, specific

gain configurations can be used as shown in Figure 10.

Bipolar Output

The MAX5152/MAX5153 can be configured for a bipo-

lar output, as shown in Figure 11. The output voltage is

given by the equation:

where NB represents the numeric value of the DAC’s

binary input code. Table 3 shows digital codes and the

corresponding output voltage for Figure 11’s circuit.
