Open Input Pins Defaults
(Continued)
In the cases where both the inverting and non-inverting pins
are open, the non-inverting condition (i.e.: voltage divider
across the output) will be the dominant condition.
Any common mode signal seen by inverting input pin should
not be allowed to exceed the Common Mode voltage range.
Exceeding the positive Common Mode voltage limit could
cause the inverting input pin voltage comparator to act as if
the inverting input pin is open. Since the comparator circuit
is not part of the switched capacitor network there is no
frequency limitation on the signal to the comparator. Any
transient on the inverting input pin which goes above the
comparator threshold will immediately cause the output to
switch to the open sensor mode. The output will return to
normal operation when the voltage on the inverting input
falls below the comparator threshold.
Supply Bypassing
For best performance the LM9040 requires a V
CC
supply
which is stable and noise free. The same 5V V
REF
supply
used for the A/D converter is the recommended V
CC
sup-
ply. During operation the device will generate current spikes
coincident with the clock edges. Inadequate bypassing will
cause excessive clock noise on the outputs, as well as
noise on the V
CC
line. The LM9040 V
CC
pin should be by-
passed with a minimum 0.1
m
F capacitor to the Signal
Ground pin, and should be located as close to the device as
possible. Some applications may require an additional
4.7
m
F tantalum capacitor, especially if there are several
other switched capacitor devices running off the same 5V
supply line. The Signal and Digital Ground pins should be
tied together as close to the device as possible.
