FAbsolute maximum ratings (Ta = 25_C) 3) Operates on a single power supply. 4) Operates on a power supply voltage as low as 3.1V. FRecommended operation conditions (Ta = 25_C) 133 Optical disc ICs FBlock diagram BH3563FV 134 Optical disc ICs FPin descriptions BH3563FV 135 Optical disc ICs FElectrical characteristics (unless otherwise noted, Ta = 25_C, VCC = 3.5V, RL = 10kΩ) BH3563FV 136 Optical disc ICs FMeasurement circuit BH3563FV 137 Optical disc ICs FApplication example BH3563FV FOperation notes (1) When the MUTE pin voltage reaches 1.5V or higher, the output voltage is muted and the bias level is output. (2) Frequency characteristics can be changed by adjusting the capacitor attached to pin 3 (pin18) or pin 5 (pin16). (3) Gain can be changed by attaching a resistor to pin 4 (pin17). (4) To prevent popping sounds due to sudden fluctuation in the mute pin voltage, attach a capacitor (approximately 1µF) to pin 7. (5) Be sure to connect the IC to a 0.1µF bypass capacitor to the power supply, at the base of the IC. 138 Optical disc ICs FElectrical characteristic curve BH3563FV FExternal dimensions (Units: mm) 1...
