Note 1:
Continuous power dissipation must also be observed.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.

All specifications are 100% tested at T
A
= +25°C.
Quiescent power-supply current is specified and tested with no load on the outputs. Quiescent power-supply current
depends on the offset voltage when a practical load is connected to the amplifier.
5:
Guaranteed by design, not production tested.
6:
Common-mode bias voltage is the voltage on BIAS and is nominally V
CC
/2.
7:
Maximum differential-output offset voltage is tested in a unity-gain configuration. V
OS
= V
OUT+
- V
OUT-
.
8:
Output power is specified by a combination of a functional output-current test, and characterization analysis.
9:
Measurement bandwidth for THD+N is 22Hz to 22kHz.
10:
Extended short-circuit conditions result in a pulsed output.
