AMP.1 is noninverting amplifier and AMP.2 ls Inverting one. The output voltage

2. MUTING
Audio muting can be accomplished by connecting
pin (9 (ripple filter) to GND as shown in Fig. 3.
Then, the bias circuits are cut off. .0 +
Amount of muting attenuation is more than 60dB. fuming BR
Precaution in muting operation is as follows.
(I). The recovery time at muting off depends on Fig.3
_ Capacitance C2, C4 and Cy in the test Circuti.
(2) I As this muting system ls operated by the share-circuit of tipple filter I
cr, the ripple rejection ratio becomes warse in a muting mode.
Note that some "POP-Noise" occur when bias is shut off with mute-on.
3. CAPACITOR C7. C8
The purpose of capacitor C7, C8 ls to prevent oscillation.
These capacitors need to be small temperature coefficient. So celamic
I capacitor is unsuitabel.
A voltage gain less than 40dB results occasionally in a parastic oscillation.
Stability for parastic‘oscillation is promoted by connecting capacitor of.
ipon, lOOOpF between pin C) and pin © (pin 6 and pin © ).
_ s The additional capacitors are recommended to be inserted.

4. PRECAUTION AT PRINT BOARD DESIGN
(1) Print Pattern board should be designed in consideration of stability for
parastic oscillation.
The following parcs-layout ls recommended.
Ist. Capacitors C6 and C10 are spaced most close to the output pin.
2rid. Capacitor C7 or C8 is spaced close to the output pin next to C6 and
3rd. Capacitor cs ls spaced close to it next to C7 and Cs.
4th. Capacitor CII ls spaced close to it next to C9.
(2) Input line (pin CD) and PU-GND line (pin CD) should not be spaced In parallel.
In the paralled layout, output current signal in PH-GND line is bed back to
Input line by electromagnetic coupling. Then it deteriorates the total
harmonic distortion, eqpebially at high audio frequency region.
(3) Undesirable terminating of capacitors deteriorates "pop" noise or TED.
Capacitors C2, C4 and C5 should be terminated to pre-GND (pinCD).
Capacitors C7, C11, and C14 should be terminated to PW-GND (pin(3).
(4) It is recommended to refer the standard print board.
