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
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
allowable power dissipation is PD

Note 5 Human body model 100 pF discharged through a 1 5 k
Note 6 Typicals are at T
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
125 C and the typical junction-to-ambient thermal resistance when board mounted is 67 C W
