1. Quiescent power supply current is specified and tested with no load. Quiescent power supply current depends
on the offset voltage when a practical load is connected to the amplifier. Guaranteed by design.
2. Common-mode bias voltage is the voltage on BIAS and is nominally V
CC
/2.
3. Output power is specified by a combination of a functional output current test and characterization analysis.
4. Measurement bandwidth for THD+N is 22Hz to 22kHz.
5. Peak voltage measured at power-on, power-off, into or out of SHDN. Bandwidth defined by A-weighted filters,
inputs at AC GND. V
