The A/D converter includes the following hardware.
These are the analog input pins of the 11-channel A/D converter. They input analog signals to be converted into
digital signals. Pins other than the one selected as the analog input pin can be used as I/O port pins.
Remark A/D converter analog input pins differ depending on products.
AMP0OUT is the output pin of operational amplifier 0.
This functions alternately as ANI1. The A/D converter can perform A/D conversion by selecting the output signal of
operational amplifier 0 as the analog input source.
AMP1OUT is the output pin of operational amplifier 1.
This functions alternately as ANI9. The A/D converter can perform A/D conversion by selecting the output signal of
operational amplifier 1 as the analog input source.
PGAOUT is the output signal of PGA.
The A/D converter can perform A/D conversion by selecting the output signal of PGA as the analog input source.
The sample & hold circuit samples each of the analog input voltages sequentially sent from the input circuit, and
sends them to the A/D voltage comparator. This circuit also holds the sampled analog input voltage during A/D
conversion.
The comparison voltage generator is connected between AV
with an analog input. The operation of the comparison voltage generator is enabled or disabled by using the ADCS
bit (bit 7 of the ADM0 register). The power consumption can be reduced by stopping the operation of the comparison
voltage generator when A/D conversion is not performed.
The A/D voltage comparator compares the sampled voltage values with the output voltage of the comparison voltage
generator. The operation of the A/D voltage comparator is enabled or disabled by using the ADCE bit (bit 0 of the
ADM0 register). The power consumption can be reduced by stopping the operation of the A/D voltage comparator
when A/D conversion is not performed.
