Nevertheless, semiconductor devices in general can malfunction or fail due to their inherent electrical sensitivity and vulnerability to physical stress. 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. @This product generates heat during normal operation. However, substandard performance or malfunction may cause the product and its peripherals to reach abnormally high temperatures. The product is often the final stage (the external output stage) of a circuit. Substandard performance or malfunction of the destination device to which the circuit supplies output may cause damage to the circuit or to the product.

Then, the bias circuits are cut off. However, caution must be exercised to the following items. (1) The recovery time from the muting operation is determined by the capacities of the ripple filter capacitor between 6 pin and GND, and of the capacitor for NF. (2) As this muting system is operated by the short-circuit of ripple filter : C5, the ripple rejection ratio becomes worse in the muting condition. At mute ON, some pop noises of breaking the bias are produced. R RSF mum sw Fig.2 1997-08-28 2/9
- MEASURES AGAINST OSCILLATION C7, C8, C9: The capacitor of polyester film having small variation of the temperature characteristics is recommended as the capacitor for oscillation prevention. R5_: Increases the oscillation allowance at output clippling of the low range frequency (100Hz or less). Since the oscillation allowance varies according of the following items, carry out the temperature test to confirm the oscillation allowance. (1) Gain to be used (Gy setting) (2) Capacity of capacitor (3) Kinds of capacitor (4) Layout of printed board It is recommended to use the capacitor having the capacity exceeding the oscillation stopping value. At using with the voltage gain Gy lowered or with the high range frequency and the oscillation becomes liable to be produced. Therefore, Application with Gy =40dB or over is advisable. Especially for using with the gain lowered in DUAL operation, insert 1000pF between NF (2 pin and 4 pin) and GND. This capacitor reduces the gain of the high range frequency and is effective for oscillation prevention. 4.

The condition in which the power supply is rapidly and repeatedly made ON/OFF, that is, the condition in which the charge is made on the external capacitor of IC is different from the conditions shown in Fig.3. 1997-08-28 3/9
