Figure 3.4 Start and stop of the analog input acquisition with delay.
Buffered analog input acquisition has several advantages over instant analog input
acquisition:
The start and stop time of acquisition (or duration of the acquisition) can be pre-
cisely controlled by hardware trigger signals.
The ADC conversion rate is configurable and the sample rate can be much
higher by using hardware sample clock signals.
Time between samples is deterministic.
3.1.3 Analog Input Low-pass Filter
The low-pass filter removes high frequency noise of the input signal and the noise
that is added by the high common-mode voltage amplifier. It can also act as an anti-
aliasing filter which avoids alias generation due to ADC conversion.
3.1.4 Analog Input Isolation
The analog input circuitry is equipped with a galvanic isolator, which can withstand a
large continuous voltage between external side and internal side. This prevents the
internal components and the host devices (e.g. PC) from damaging when such fault
condition happens.
