Note 2: All specifications are 100% tested at TA = +25°C.
Note 3: 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.
Note 4: Common-mode bias voltage is the voltage on BIAS and is nominally VCC/2.
Note 5: Maximum differential-output offset voltage is tested in a unity-gain configuration. VOS = VOUT+ - VOUT-.
Note 6: Output power is specified by a combination of a functional output-current test, and characterization analysis.
Note 7: Guaranteed by design, not production tested.
Note 8: Measurement bandwidth for THD + N is 22Hz to 22kHz.
Note 9: Extended short-circuit conditions result in a pulsed output.
Typical Operating Characteristics
(VCC = 5V, THD + N measurement bandwidth = 22Hz to 22kHz, TA = +25°C, unless otherwise noted.)
