saved, allowing the MAX5154/MAX5155 to recall the
output state prior to entering shutdown when returning
to normal mode. Exit shutdown by recalling the previ-
ous condition or by updating the DAC with new infor-
mation. When returning to normal operation (exiting
shutdown), wait 20μs for output stabilization.
S erial Interfac e
The MAX5154/MAX5155 3-wire serial interface is com-
patible with both Microwire (Figure 2) and SPI/QSPI
(Figure 3) serial-interface standards. The 16-bit serial
input word consists of an address bit, two control bits,
12 bits of data (MSB to LSB), and one sub bit as shown
in Figure 4. The address and control bits determine the
MAX5154/ MAX5155’s response, as outlined in Table 1.
