See Figure 4 for a block diagram of the input multiplexer on the TSC2003, the differential input of the ADC, and
the converter's differential reference.
When the converter enters the Hold mode, the voltage difference between the +IN and –IN inputs (see Figure 4)
is captured on the internal capacitor array. The input current on the analog inputs depends on the conversion
rate of the device. During the sample period, the source must charge the internal sampling capacitor (typically
25 pF). After the capacitor has been fully charged, there is no further input current. The amount of charge
transfer from the analog source to the converter is a function of conversion rate.
