The digital inputs are compatible with CMOS logic. In
order to save power and reduce input to output cou-
pling, SCLK and DIN input buffers are powered down
immediately after completion of shifting 16 bits into the
input shift register. A high to low transition at CS pow-
ers up SCLK and DIN input buffers.

The typical application circuit (Figure 3) shows the
MAX5741 configured for a unipolar output, where the
output voltages and the reference inputs have the
same polarity. Table 3 lists the unipolar output codes.
The MAX5741 can be configured for bipolar operation
using a dual supply op amp (Figure 4). The transfer
function for bipolar operation is:
