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. Improvement of ripple rejection is possible by connecting series RC between pin 11 and pin 14 (15 k + 2.2 F;
3. An open pin (n.c.) is interpreted as HIGH.

The curves are typical and valid for ripple frequencies between 50 Hz and 3 kHz.
Conditions: input signal: f = 5.5 MHz, 10 mV (RMS value); ripple on V
ripple rejection measurement: unweighted RMS.
(1) Without RC.
(2) With R = 15 k and C = 2.2 F.
2.7 k between pin 15 and ground. In this event the input impedance is 490 .
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.
