Applications
Audio Muting Function
Figure 8 shows the PI5A100 in an audio card muting application.
The original problem was one of excessive popping/clicking noise
appearing when connecting disconnecting external loads, and at
poweron/off.ThePI5A100performsamutingfunctionbygrounding
the outputs at power on/off and during the transition time. The
32 headset impedance demands a very low and very flat switch-
on resistance to reduce THD and signal loss.
Figure 10: The PI5A100 momentarily mutes the stereo outputs by connecting them to ground during transition times.
Paralleling two sections of the PI5A100 produces a Ron of 2.5
with an unsurpassed
±0.5 flatness.
To handle AC signals it was necessary to power the device with
±3V provided by two Zener diodes: Z1 and Z2. The select and
Enable control signals are shifted by using twpo 2.5VZener diodes
Z3,Z4 and pull down resistors connected to -3V.
