Product data sheet
7.3 Timing output
7.4 Timing complete conversion signal
The ADC0808S generates an adjustable clock output signal on pin CCS called Complete
Conversion Signal, which can be used to control the acquisition of converted output data
to the digital circuit connected to the ADC0808S output data bus.
Two logic input pins DEL0 and DEL1 control the delay of the edge of the CCS signal to
achieve an optimal position in the stable, usable zone of the data as shown in
Table 7.
Pin CCSSEL selects the CCS frequency; see
Table 8.
