Note 1: All specifications are 100% tested at T
Note 2: Quiescent power-supply current is specified and tested with no load. Quiescent power-supply current depends on the offset
Note 3: Common-mode bias voltage is the voltage on BIAS and is nominally V
Note 4: Output power is specified by a combination of a functional output current test and characterization analysis.
Note 5: Measurement bandwidth for THD+N is 22Hz to 22kHz.
Note 6: Peak voltage measured at power-on, power-off, into or out of SHDN. Bandwidth defined by A-weighted filters, inputs at AC
