puts become high impedance, and the serial inter-
face remains active. Data in the input registers is
saved, allowing the MAX5150/MAX5151 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 20s for output stabilization.
Serial Interface
The MAX5150/MAX5151 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,
and 13 bits of data (MSB to LSB) as shown in Figure 4.
