format. Observe the SCLK to DOUT valid timing
characteristic. Clock data into the μP on SCLK
’
s ris-
ing edge.
3) Pull
CS
high at or after the 24th falling clock edge. If
CS
remains low, trailing zeros are clocked out after
the least significant bit (D0 = LSB).
4) With
CS
high, wait at least 50ns (t
CSW
) before start-
ing a new conversion by pulling
CS
low. A conver-
sion can be aborted by pulling
CS
high before the
conversion ends. Wait at least 50ns before starting a
new conversion.
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 LSB (D0) and
CS
has been kept low, DOUT sends trailing zeros.
SPI and MICROWIRE Interfaces
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 16-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 D8.
The third 8-bit data stream contains D7 through D0.
QSPI Interface
Using the high-speed QSPI interface with CPOL = 0
and CPHA = 0, the MAX1162 supports a maximum
f
SCLK
of 4.8MHz. Figure 11a shows the MAX1162 con-
nected to a QSPI master and Figure 11b shows the
associated interface timing.
