VAREF VAGND

Figure 74 shows the timing diagram of a complete conversion. For simplicity, the figure

depicts the waveforms in idealized form and do not provide precise timing information.

For ADC characteristics and timing parameters refer to the Section “AC Characteristics”

of the AT89C51CC03 datasheet.

Note:

Tsetup min = 4 us

Tconv=11 clock ADC = 1sample and hold + 10 bit conversion

The user must ensure that 4 us minimum time between setting ADEN and the start of the first conversion.
