Notes
1.
The output signal at pin 7 can only be measured when mute is disabled. This is achieved by inserting a resistor of
2.7 k
between pin 15 and ground. In this event the input impedance is 490
.
Improvement of ripple rejection is possible by connecting series RC between pin 11 and pin 14 (15 k
+ 2.2
μ
F;
see Fig.5) for a supply voltage of 4.5 to 5.5 V. The rejection of ripple frequencies up to 3 kHz is improved, but up to
200 kHz is worse; see Fig.3.
An open pin (n.c.) is interpreted as HIGH.
