Typical Performance Characteristics (Continued)
Application Information
MUTE MODE
The muting function of the LM4766 allows the user to mute
the music going into the amplifier by drawing more than
0.5mA out of each mute pin on the device. This is accom-
plished as shown in the Typical Application Circuit where the
resistor R
M is chosen with reference to your negative supply
voltage and is used in conjunction with a switch. The switch
when opened cuts off the current flow from pin 6 or 11 to
V
EE, thus placing the LM4766 into mute mode. Refer to the
Mute Attenuation vs Mute Current curves in the Typical
Performance Characteristics section for values of attenu-
ation per current out of pins 6 or 11. The resistance R
M is
calculated by the following equation:
R
M ≤ (|VEE| 2.6V)/Ipin6
where I
pin6 =Ipin11 ≥ 0.5mA.
Both pins 6 and 11 can be tied together so that only one
resistor and capacitor are required for the mute function. The
mute resistance must be chosen such that greater than 1mA
is pulled through the resistor R
M so that each amplifier is fully
