Note 6:
The human body model is a 100 pF capacitor discharged through a 1.5 k
resistor into each pin. The machine model is a 200 pF capacitor discharged di-
rectly into each pin.
Note 7:
See AN-450 “Surface Mounting Methods and Their Effect on Product Reliability” or the section titied “Surtace Mount” found in any post 1986 National Semi-
conductor Linear Data Book for other methods of soldering surtace mount devices.
Note 8:
Two on-ohip diodes are tied to each analog input as shown below. They will forward-conduct for analog input voltages one diode drop below ground or one
diode drop greater than V
supply. Be careful during testing at low V
levels (+4.5V), as high level analog inputs (+5V) can cause an input diode to conduct, especially
at elevated temperatures, which will cause errors In the conversion result. The specification allows 50 mV forward bias of either diode; this means that as long as
the analog V
does not exceed the supply voltage by more than 50 mV, the output code will be oorrect. Exceeding this range on an unselected channel will corrupt
the reading of a selected channel. If AV
and DV
are minimum (4.5 V
DC
) and full scale must be
≤
+4.55 V
DC
.
Note 9:
No connection exists between AV
+
and DV
+
on the chip.
To guarantee accuracy, it is required that the AV
+
and DV
+
be connected together to a power supply with separate bypass filter at eacn V
+
pin.
Note 10:
One LSB is referenced to 10 bits of resolution.
Note 11:
Typicals are at T
J
= T
A
= 25C and represent most likely pararmetric norm.
Note 12:
Tested limits are guaranteed to National’s AOQL (Average Outgolng Quality Level).
Note 13:
Total unadjusted error includes offset, full-scale, linearity, multiplexer, and hold step errors.
Note 14:
The DC common-mode error is measured in the differential multiplexer mode with the assigned positive and negative input channels shorted together.
Note 15:
Channel leakage current is measured after the channel selection.
Note 16:
All the timing specifications are tested at the TTL logic levels, V
IL
= 0.8V for a falling edge and V
IH
= 2.0V for a rising. TRl-STATE voltage level is forced
to 1.4V.
Note 17:
The voltage applied to the digital inputs will affect the current drain during power down. These devices are tested with CMOS logic levels (logic Low = 0V
and logic High = 5V). TTL levels increase the current, during power down, to about 300 μA.
