Note 5

Human body model 100 pF discharged through a 15 kX resistor Machine model ESD rating is 200V

Note 6

See AN-450 ‘‘Surface Mounting Methods and Their Effect on Product Reliability’’ or the section titled ‘‘Surface Mount’’ found in a current National

Semiconductor Linear Data Book for other methods of soldering surface mount devices

Note 7

Note 8

Tested limits are guaranteed to National’s AOQL (Average Outgoing Quality Level)

Note 9

Integral Linearity Error is the maximum deviation from a straight line between the

measured offset and full scale endpoints

Note 10

Dynamic testing of the ADC12062 is done using the ADC IN input The input multiplexer adds harmonic distortion at high frequencies See the graph in the

Typical Performance Characteristics section for a typical graph of THD performance vs input frequency with and without the input multiplexer

Note 11

The signal-to-noise ratio is the ratio of the signal amplitude to the background noise level Harmonics of the input signal are not included in its calculation

Note 12

The contributions from the first nine harmonics are used in the calculation of the THD

Note 13

176)602

Note 14

The digital power supply current takes up to 10 seconds to decay to its final value after PD is pulled low This prohibits production testing of the standby

current Some parts may exhibit significantly higher standby currents than the 20 mA typical

Note 15

Power Supply Sensitivity is defined as the change in the Offset Error or the Full Scale Error due to a change in the supply voltage
