(1) Maximum conversion rate with respect to the typical internal oscillator speed (i.e.: 6 MSPS * (tc/t2).
SINGLE CONVERSION MODE
In single conversion mode, a single conversion of the selected analog input channels is performed. The single conversion
mode is selected by setting bit 1 of control register 0 to 1.
A single conversion is initiated by pulsing the CONVST input. On the falling edge of CONVST, the sample and hold stages
of the selected analog inputs are placed into hold simultaneously, and the conversion sequence for the selected channels
is started.
The conversion clock in single conversion mode is generated internally using a clock oscillator circuit. The signal DATA_AV
(data available) becomes active when the trigger level is reached and indicates that the converted sample(s) is (are) written
into the FIFO and can be read out. The trigger level in the single conversion mode can be selected according to Table 13.
Figure 1 shows the timing of the single conversion mode. In this mode, up to four analog input channels can be selected
to be sampled simultaneously (see Table 2).

Figure 24. Timing of Single Conversion Mode
The time (t2) between consecutive starts of single conversions is dependent on the number of selected analog input
channels. The time tDATA_AV, until DATA_AV becomes active is given by: tDATA_AV = tpipe + n × tc. This equation is valid for
a trigger level which is equivalent to the number of selected analog input channels. For all other trigger level conditions refer
to the timing specifications of single conversion mode.
