A/D Converter
In the SAB 80C515A a new high performance / high-speed 8-channel 10-bit A/D-Converter
(ADC) is implemented. Its successive approximation technique provides 7
μ
s conversion time
(
f
OSC
= 16 MHz). The conversion principle is upward compatible to the one used in the
SAB 80C515. The main functional blocks are shown in figure 3.
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 genuine10-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.
The ADC is clocked (
f
ADC
) with
f
OSC
/8. Because of the ADC's maximum clock frequency of
2 MHz the prescaler (divide-by-2) has to be enabled (set Bit ADCL in SFR ADCON 1) when the
oscillator frequency (
f
OSC
) is higher than 16 MHz.
