It is the responsibility of the buyer, when utilizing TOSHIBA products, to observe standards of safety, and to avoid situations in which a malfunction or failure of a TOSHIBA product could cause loss of human life, bodily injury or damage to property. In developing your designs, please ensure that TOSHIBA products are used within specified operating ranges as set forth in the most recent products specifications. Also, please keep in mind the precautions and conditions set forth in the TOSHIBA Semiconductor Reliability Handbook 1997-04-07 1/11

MODE SW (pin®) @ It is necessary to connect an external pull-down resistor with the terminal of MODE SW (pin@), in case that this IC mode doesn’t Vee operate normally due to external noise etc. L. k @ Reducing a pop sound . It is advised to connect R1, R2 and C with the terminal of Rp c MODE SW (pin@), to reduce a pop sound is switchover between A single IF mode and dual IF mode (see Fig.1). It is better that the constants are RISR25100k0, C=1yF at Fig.1 Mode switch circuit Vcc = 1.2V. As for the constants, select the optimum one reducing a pop sound depending on each a set carefully. ©@ Operating amplifier etc. is decided by condition of mode switch. It is as follows. | INPUT TERMINAL | OUTPUT TERMINAL | OPERATING AMP. ; OUTa (pin®) IF, BUFA Dual IF mode IF INa (pind) DET OUT (pin) AF IF INg (pin@) OUTR (pin@) IFg, BUFR IF INa (pin®) DET OUT (pin®) Single IF mode INa (pin@) OUTa (pin®) INg (pind) OUTs (pin®) Table 1 Operating amplifier etc. by mode switch condition 2. IF IN (pin@@) External parts (ceramic filter etc.) of IF amplifier should be connected Vcc, terminal with common terminal of external parts, because IF amplifier circuits operate on Vc¢c1 voltage. In case that these external parts are connected with GND reference etc., there is a possibility that this circuit doesn’t operate normally at large signal input. 1997-04-07 4/11

In case that the muting function isn't used. In case that the muting function isn’t used, the terminal of MT IN (pin®3) and LPF (pin®$) should be opened. In case that these terminal connected with Vcc or GND, internal circuit doesn’t operate normally. It is necessary to connect an external capacitor (C=0.01,F) with the terminal of MT IN (pin@3) and LPF (pin{), in case that the muting function operates due to external noise etc. 5. INPUT OF AUDIO SIGNAL The audio signal should be applied to the terminal of INq (pin@) or INg (pin@®) through a coupling capacitor because buffer amplifier is operated by Vpef- In case that DC current or DC voltage is applied to the terminal of INa (pin®) or INg (pin®), the internal circuit has unbalance and buffer amplifier doesn’t operate normally. 1997-04-07 5/11
