Figure 45. ADC Analog Input Capacitance (Cin) Across Frequency
Two example driving circuit configurations are shown in Figure 46 and Figure 47 – one optimized for low
bandwidth (low input frequencies) and the other one for high bandwidth to support higher input frequencies.
In Figure 46, an external R-C-R filter using 22pF has been used. Together with the series inductor (39nH), this
combination forms a filter and absorbs the sampling glitches. Due to the large capacitor (22pF) in the R-C-R and
the 15
resistors in series with each input pin, the drive circuit has low bandwidth and supports low input
frequencies (<100MHz).
To support high input frequencies (up to about 300MHz, see Figure 47), the capacitance used in the R-C-R is
reduced to 3.3pF and the series inductors are shorted out. Together with the lower series resistors (5
), this
drive circuit provides high bandwidth and supports high input frequencies.
Transformers such as ADT1-1WT or ETC1-1-13 can be used up to 300MHz.
Without the external R-C-R filter, the drive circuit has very high bandwidth & can support very high input
frequencies (> 300MHz). For example, a transmission line transformer such as ADTL2-18 can be used
Note that both the drive circuits have been terminated by 50 ohms near the ADC side. The termination is
accomplished by a 25 ohms resistor from each input to the 1.5V common-mode (VCM) from the device. This
allows the analog inputs to be biased around the required common-mode voltage.
