Electrical Characteristics
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 output when the undriven input 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.
