2.3 Signal Connection and Pin Assignment
2.3.1 Analog Input Signal Connection
An analog input channel measures the voltage (VS) of the external source. The volt-
age difference between the positive terminal and the negative terminal is being mea-
sured.
The voltage is then amplified or attenuated by a programmable gain instrumentation
amplifier (PGIA), conditioned by a low-pass filter (LPF), and sampled and converted
into a digital form of data by an analog-to-digital converter (ADC). The ADC of every
channel samples the signal at the same time, and this architecture is thus called
simultaneous sampling.
Analog input signal connection and internal functional block diagram is shown in Fig-
ure 2. 1.
