4 / 12 page TA8271HQ 2004-05-10 4 3. Muting Function (pin 22) By means of controlling pin 22 less than 0.5 V, it can make the audio muting condition. The muting time constant is decided by R1, C4 and C8 and these parts is related the pop noise at power ON/OFF. The series resistance; R1 must be set up less than 5 kΩ. The muting function have to be controlled by a transistor, FET and µ-COM port which has IMUTE > 50 µA ability. – Conventional Method – VCC Large current capacity switch BATTERY VCC FROM MICROCOMPUTER BATTERY RELAY VCC Small current capacity switch BATTERY Stand-By VCC DIRECTLY FROM MICROCOMPUTER BATTERY Stand-By – Stand-by Switch Method – Figure 3 Figure 5 Mute Attenuation − VMUTE (V) Point A voltage: VMUTE (V) ATT – VMUTE R1 = 2.2 kΩ R1 = 5 kΩ VCC = 13.2 V Po = 10 W RL = 4 Ω f = 1 kHz −100 1.2 1.4 1.6 1.8 2.0 2.2 2.4 2.6 2.8 −80 −60 −40 −30 −20 0 −10 −90 −70 −50 Figure 4 Muting Function R1 I (20 µA) 22 IMUTE IMUTE (OFF) A VMUTE 25 |
