Electrical Characteristics

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 is P
= (T
T
)/
θ
or the number given in the Absolute Maximum Ratings, whichever is lower. For the LMC1982CIN, T
JMAX
=
+125C, and the typical junction-to-ambient thermal resistance, when board mounted, is 67C/W.
Note 5:
Human body model; 100 pF discharged through a 1.5 k
resistor.
Note 6:
Typicals are at T
J
= +25C and represent the most likely parametric norm.
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.
Note 10:
Enhanced Stereo Cross Coupling is a measure of the ratio between the undriven right channel output signal and the driven left channel output signal. It
is measured by driving the left inputs with a 300 mV
rms
signal while the right inputs are grounded.
