Figure 2-31 shows the equivalent circuitry for the input
channels of the PAC193X devices. ESD protection
diodes include two 40V breakdown diodes. Input
leakage current is very low (no DC bias current). The
switched capacitor sampling circuits shown as a switch
with equivalent series resistance and sampling
capacitor. The switches work at 1024 samples per
second (SPS) maximum, independent of sampling rate
(at 8 SPS, the device is sleeping in between samples).
Input impedance for each input is about 32 MΩ.
