Electrical Characteristics (Notes)
Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed
specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test condi-
tions.
Note 2:
All voltages are measured with respect to GND = AGND = DGND = DGND
(I/O)
= 0V, unless otherwise specified.
Note 3:
When the input voltage (V
IN
) at any pin exceeds the power supplies (V
IN
<
GND or V
IN
>
V
A
or V
D
), the current at that pin should be limited to 25 mA. The
50 mA maximum package input current rating limits the number of pins that can simultaneously safely exceed the power supplies with an input current of 25 mA to
two.
Note 4:
The maximum power dissipation must be derated at elevated temperatures and is dictated by T
,
θ
and the ambient temperature, T
. The maximum
allowable power dissipation at any temperature is P
D
= (T
Jmax
–T
A
)/
θ
JA
. T
Jmax
= 150C for this device. The typical thermal resistance
θ
JA
of this part when board
mounted is 52C/W for the V52A PLCC package.
Note 5:
Human body model, 100 pF capacitor discharged through a 1.5
resistor.
Note 6:
See AN450 “Surface Mounting Methods and Their Effect on Product Reliability” or the section titled “Surface Mount” found in any post 1986 National Semi-
conductor Linear Data Book for other methods of soldering surface mount devices.
Note 7:
A Zener diode clamps the OS analog input to AGND as shown below. This input protection, in combination with the external clamp capacitor and the output
impedance of the CCD, prevents damage to the LM9800 from transients during power-up.
Note 8:
To guarantee accuracy, it is required that V
A
and V
D
be connected together to the same power supply with separate bypass capacitors at each supply pin.
Note 9:
Typicals are at T
J
= T
A
= 25C, f
MCLK
= 20MHz, and represent most likely parametric norm.
Note 10:
Tested limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).
