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.
2. Common-mode bias voltage is the voltage on BIAS and is nominally V
CC
/2.
3. Guaranteed by design.
4. Guaranteed by design.
5. Measurement bandwidth for THD+N is 22Hz to 22kHz.
6. Peak voltage measured at power-on, power-off, into or out of SHDN. Bandwidth defined by A-weighted filters,
inputs at AC GND. V
