2. Individual pins and their operations
0.47 to 2.2 µF recommended.
Capacitance is reduced, so the off level in input equivalent becomes lower in
the bass frequency range. We recommend 1 to 10 µF.
Any time delay can be obtained by adequate choice of C3 and R1. We
recommend 150 k to 500 kfor R1.
For diode when pin 8 is used to drive external transistors. A 1 kresistor is
recommended.
VIN
Input signal level, VIN – dBm
As shown above, when input level is raised and the pin 2 voltage reaches the VTH-H level of the comparator, pins 6 and 8 turn
.over. (VIN = –45 dBm).
Pin 6 is for driving plungers, When it is on the ‘‘L’’ side, pin 6 turns on and can draw current up to 600 mA maximum
(restricted by duty-cycle chart). It is not to be on continuously for more than 3 seconds.
. Pin 7 is a diode that prevents reverse voltages induced when the plunger is turned off from on.
. Pin 8 functions in phase with pin 6 and can drive external transistors (such as for MUTE ).
