ANALOG INPUT
Figure 2 shows a block diagram of the input multiplexer on
the TSC2046, the differential input of the ADC, and the
differential reference of the converter. Table 1 and Table 2
show the relationship between the A2, A1, A0, and
SER/DFR control bits and the configuration of the TSC2046.
The control bits are provided serially via the DIN pin—see the
Digital Interface section of this data sheet for more details.
When the converter enters the hold mode, the voltage
difference between the +IN and –IN inputs (shown in
Figure 2) is captured on the internal capacitor array. The
input current into the analog inputs depends on the
conversion rate of the device. During the sample period, the
source must charge the internal sampling capacitor (typically
25pF). After the capacitor is fully charged, there is no further
input current. The rate of charge transfer from the analog
source to the converter is a function of conversion rate.
