AC Electrical Characteristics
(Continued)
Note 7:
The inputs are protected as shown below. Input voltage magnitudes up to 5V above V
A
or to 5V below GND will not damage this device, provided current
is limited per (Note 3). However, errors in theA/D conversion can occur if the input goes above V
A
or below GND by more than 100 mV.As an example, if V
A
is 4.75V,
the full-scale input voltage must be
≤
4.85V to ensure accurate conversions.
Note 8:
To guarantee accuracy, it is required that |V
A
–V
D
|
≤
100 mV and separate bypass capacitors are used at each power supply pin.
Note 9:
With the test condition for V
REF
= +2.0V, the 12-bit LSB is 488 μV.
Note 10:
Typical figures are at T
A
= T
J
= 25C, and represent most likely parametric norms. Test limits are guaranteed to National’sAOQL (Average Outgoing Qual-
ity Level).
Note 11:
Tested limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).
Note 12:
Integral Non-Linearity is defined as the deviation of the analog value, expressed in LSBs, from the straight line that passes through positive full-scale and
zero.
Note 13:
Timing specifications are tested at the TTL logic levels, V
IL
0.4V for a falling edge and V
IH
= 2.4V for a rising edge. TRI-STATE output voltage is forced
to 1.4V.
Note 14:
Optimum SNR performance will be obtained by keeping the reference input in the 1.8V to 2.2V range. The LM4041CIM3-ADJ (SOT-23 package), the
LM4041CIZ-ADJ (TO-92 package), or the LM4041CIM-ADJ (SO-8 package) bandgap voltage reference is recommended for this application.
