BA7735FS FOperation notes (1) Since muting measures are not taken in the IC when the power supply is turned on or off, these measures should be taken externally if necessary. (2) The gain for the output amplifier should be set to a value between 0 and 12dB. (3) DC offset voltage may be produced, depending on the EVR control point. If this is a problem, insert a coupling capacitor at the point where connection is made to the next stage. (4) If DC offset voltage is a problem when switching modes, co.
