The AT43USB353M features a 10-bit successive approximation ADC. The ADC is connected
to a 12-channel Analog Multiplexer to pins AD0 – AD11. The ADC contains a Sample and
Hold Amplifier that ensures that the input voltage to the ADC is held at a constant level during
conversion. A block diagram of the ADC is shown in Figure 15.
The reference voltage of the ADC is internally connected to the CEXTA voltage regulator.
