ICs for Audio Common Use

■ Technical Information (continued)

[2] Application note (continued)

11. Two IC use (continued)

1) Supply terminal

Short-circuiting each other, insert an electrolytic capacitor of approx. 2 200 µF into the supply terminals.

However, if sufficient characteristics of the ripple rejection can not be obtained, use an even larger capacitor

or insert a 2 200 µF capacitor into each IC.

The best sound quality can be obtained by inserting a 2 200 µF capacitor near the terminal of each IC.

2) Standby terminal (pin 5)

Even if the standby terminals are connected with each other, that does not result in an abnormal operation.

Connect with the microcomputer after connecting the standby pins with each other. At that time, the current

flowing into the standby terminal is twice as large as the current which is described in 1. Standby function.

3) Muting terminal (pin 7)

An abnormal operation does not occur even if the muting terminals are short-circuited with each other.

The muting time constant changes when two ICs connection is made. If the CR constants are set at twice

and 1/2 time respectively, the time constant value becomes as same as the value when one IC is used.

4) Beep sound input terminal (pin 10)

Even if the the beep sound input terminals are short-circuited each other, that does not result in an abnormal

operation.

However, if there is a temperature difference between ICs, there may be a fluctuation of the output offset.

In order to avoid such a phenomenon, connect the ICs with each other through a resistor (47 kΩ).

5) Ripple filter terminal (pin 12)

Even if the ripple filter terminals are short-circuited each other, that does not result in an abnormal

operation.

However, if the standby of each IC is individually controlled, the short-circuiting is not allowed. Use the

circuit after connecting a capacitor (33 µF) to each IC.

6) If one IC is used as a combination of L or R of the front and the rear, the cross-talk between the L and R

increases. The circuit shown by figure 8 becomes thermally advantageous when there is a difference in the

output between the front and rear.

7) Arrangement of IC

The larger the distance between the two ICs is, the more advantageous the heat radiation design becomes.
