Muting Audio muting can be accomplished by connecting pin® (ripple filter) to GND as shown in (Fig.3). 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 pin® and GND, and of the capacitor for NF. (2) As this muting system is operated by the short-circuit of Fe Muting SW ripple filter : C5, the ripple rejection ratio becomes worse in the muting condition. (Fig.3) At mute ON, some pop noise of breaking the bias are '9- produced. The output waveform at muting ON riled / OFF during BTL, are shown in ri; ttt eT RELL] (Fig.4).

TOSHIBA TA7280,81P 3. Measures against oscillation C7, Cg, Cg, C12 : The capacitor of polyester film having small variation of the temperature characteristics is recommended as the capacitor for oscillation prevention. C12 : Reduces the gain in the high range frequency (150kHz or over) and increases the oscillation allowance. Rs : Increases the oscillation allowance at output cripping of the low range frequency (100Hz or less). Since the oscillation allowance varies according to the following item, 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 (Pin®@ and Pin@) and GND. This capacitor reduces the gain of the high range frequency and is effective for oscillation prevention. 4.
