Note 1:
Continuous power dissipation must also be observed.
Note 2:
All specifications are tested at T
A
= +25°C. Specifications over temperature (T

to T

) are not production tested,
and guaranteed by design.
Note 3:
Quiescent power-supply current is specified and tested with no load. Quiescent power-supply current depends on the off-
set voltage when a practical load is connected to the amplifier.
Note 4:
Common-mode bias voltage is the voltage on BIAS and is nominally V

Note 6:
The amplifier input IN- is AC-coupled to GND through C

.
Note 7:
Output power is specified by a combination of a functional output current test and characterization analysis.
Note 8:
Measurement bandwidth for THD+N is 22Hz to 22kHz.
Note 9:
Extended short-circuit conditions result in a pulsed output.
Note 10:
Time for V
