3V Operation
Table 5. Electrical Characteristics – 3V Supply, T
1. Quiescent power supply current is specified and tested with no load. Quiescent power supply current depends on
2. Common-mode bias voltage is the voltage on BIAS and is nominally V
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,
