14. Test information
14.1 Static characterization
The quiescent current has been measured without any load impedance (Figure 4).
Figure 6 shows three areas: operating, mute and standby. It shows that the DC switching
levels of the mute and standby respectively depends on the supply voltage level.
RL = ∞
Band-pass = 22 Hz to 22 kHz.
(1) VCC =3V.
(2) VCC =5V.
(3) VCC =12V.
