Therearesomeimmediatetrade-offsinRSandCINwithout
needing a full circuit analysis. Increasing RS and CIN can
provide the following benefits:
1. Due to the LTC2451’s input sampling algorithm, the
input current drawn by the input pin (IN) over a con-
version cycle is 50nA. A high RS CIN attenuates the
high frequency components of the input current, and
RS values up to 1k result in <1LSB additional INL.
2. The bandwidth from VSIG is reduced at the input pin.
This bandwidth reduction isolates the ADC from high
frequency signals, and as such provides simple anti-
aliasing and input noise reduction.
3. Switching transients generated by the ADC are attenu-
ated before they go back to the signal source.
4. A large CIN gives a better AC ground at the input pin,
helping reduce reflections back to the signal source.
5. Increasing RS protects the ADC by limiting the current
during an outside-the-rails fault condition.
There is a limit to how large RS CIN should be for a given
application. Increasing RS beyond a given point increases
Figure 12. Measured INL vs Input Voltage,
CIN = 0.1F, VCC = 5V, TA = 25°C
the voltage drop across RS due to the input current,
to the point that significant measurement errors exist.
Additionally, for some applications, increasing the RSCIN
product too much may unacceptably attenuate the signal
at frequencies of interest.
For most applications, it is desirable to implement CIN
as a high quality 0.1F ceramic capacitor and RS ≤ 1k.
This capacitor should be located as close as possible to
the input pin. Furthermore, the area encompassed by
this circuit path, as well as the path length, should be
minimized.
In the case of a 2-wire sensor that is not remotely
grounded, it is desirable to split RS and place series
resistors in the ADC input line and in the sensor ground
return line, which should be tied to the ADC GND pin using
a star connection topology.
Figure 12 shows the measured LTC2451 INL versus the
input voltage as a function of RS value with an input ca-
pacitor CIN = 0.1F.
In some cases, RS can be increased above these guide-
