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
conditions.
Note 2:
All voltages are specified with respect to ground.
Note 3:
When the input voltage (V
IN
) at any pin exceeds the power supply voltages (V
IN
k
V
b
or V
IN
l
V
a
) the absolute value of the current at that pin should be
limited to 5 mA or less. The 20 mA package input current limits the number of pins that can exceed the power supply voltages with 5 mA current limit to four.
Note 4:
The maximum power dissipation must be de-rated at elevated temperatures and is dictated by T
JMAX
,
w

, and the ambient temperature T
A
. The maximum
allowable power dissipation is PD

Note 7:
Limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).
Note 8:
The Input-Input Isolation is tested by driving one input and measuring the front outputs when the undriven inputs are selected.
Note 9:
The Volume Step Size is defined as the change in attenuation between any two adjacent volume attenuation settings. The nominal Volume Step Size is
2 dB.
Note 10:
The Fader Step Size is defined as the change in attenuation between any two adjacent fader attenuation settings. The nominal Volume Step Size is 2 dB.
