M
mum (1.7MHz), reading the data after each conversion
(during the acquisition time) results in lower throughput
(about 70ksps max) than reading the data during con-
versions, 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 MAX194 in its simplest
operational configuration.
