... With CS low, data is clocked into the register on the rising edge of SCLK. The maximum serial clock frequency guaranteed for proper operation is 10MHz for MAX5170 and 6MHz for MAX5172. See Figure 5 for a detailed timing diagram of the serial interface. The serial-data output, DOUT, is the internal shift regis- ter’ ...

... Applications Information Unipolar Output Figure 6 shows the MAX5170/MAX5172 configured for unipolar, rail-to-rail operation with a gain of +1.638V/V. Table 2 lists the codes for unipolar output voltages. The maximum output voltage is limited introduce an offset voltage as shown in Figure 7 and described in the Offset and Buffer Configurations section. ...

... To set the gain of the output amplifier to 1, connect OS to OUT. Daisy-Chaining Devices The serial data output pin (DOUT) allows multiple MAX5170/MAX5172s to be daisy-chained together, as shown in Figure 9. The advantage of this is that only two lines are needed to control all the DACs on the line. The disadvantage is that it takes n commands to program the DACs ...
