Data can be output in three 8-bit sequences or continu-
ously. The bytes contain the results of the conversion
padded with eight leading zeros before the MSB. If the
serial clock has not been idled after the sub-bits (S1
and S0) and CS has been kept low, DOUT sends trail-
ing zeros.

When using the SPI (Figure 10a) or MICROWIRE
(Figure 10b) interfaces, set CPOL = 0 and CPHA = 0.
Conversion begins with a falling edge on CS (Figure
10c). Three consecutive 8-bit readings are necessary
to obtain the entire 14-bit result from the ADC. DOUT
data transitions on the serial clock’s falling edge. The
first 8-bit data stream contains all leading zeros. The
second 8-bit data stream contains the MSB through D6.
The third 8-bit data stream contains D5 through D0 fol-
lowed by S1 and S0.
Using the high-speed QSPI interface with CPOL = 0
and CPHA = 0, the MAX1062 supports a maximum
