Data is clocked out on SCLK’s falling edge. Clock
data in on SCLK’s rising edge or, for clock speeds
above 2.5MHz, on the following falling edge to meet
the maximum SCLK-to-DOUT timing specification
(Figure 7). The maximum SCLK speed is 5MHz. See
the Operating Modes and SPI/QSPI Interfaces section
for additional information. When the conversion clock
is near its maximum (1.7MHz), reading the data after
each conversion (during the acquisition time) results
in lower throughput (about 70ksps max) than reading
the data during conversions, because it takes longer
than the minimum input acquisition time (four cycles
at 1.7MHz) to clock 16 data bits at 5Mbps. After the
data has been clocked in, leave some time (about
1μs) for any coupled noise on AIN to settle before
beginning the next conversion.
Whichever method is chosen for reading the data, con-
versions can be individually initiated by bringing
CONV
low, or they can occur continuously by connecting
EOC
to
CONV
. Figure 8 shows the MAX195 in its simplest
operational configuration.
