A/D Converter
In the SAB 80C517A a new high performance / high-speed 12-channel 10-bit A/D-Converter is
implemented. Its successive approximation technique provides 7
s con-version time (f
OSC= 16
MHz). The conversion principle is upward compatible to the one used in the SAB 80C517. The
main functional blocks are shown in figure 4.
The comparator is a fully differential comparator for a high power supply rejection ratio and very
low offset voltages. The capacitor network is binary weighted providing genuine 10-bit
resolution.
The table below shows the sample time T S and the conversion time T C, which are dependend
on f OSC and a new prescaler (see also Bit ADCL in SFR ADCON 1).
