BD5460 is a low power Class D amplifier that can be acclimated in low ability applications like handheld audio devices. BD5460 does not crave an LC clarify at the apostle achievement and can be apprenticed application a battery, The standby accepted of BA5460 is about aught and there is no about-face ON / OFF clicks. The BD5460 can bear 0.8 watts into an 8 ohm apostle at 3.6 V accumulation voltage. The ability accumulation voltage ambit is from 2.5 to 6.5 V DC. The IC has a congenital standby function, abbreviate ambit protection, thermal abeyance and beneath voltage lockout. Two chic D amplifier circuits application BD5460 are apparent below. The aboriginal one is a cogwheel ascribe chic D amplifier while the additional one is a individual concluded ascribe chic D amplifier. The 0.1uF capacitors (C1, C2, C3 and C4) are ascribe DC decoupling capacitors. The lower cut off abundance of the amplifier depends on these capacitors. 10uF capacitors (C5 and C6) are the ability accumulation filters. S1 and S2 are the abeyance switches. Abutting the C1 pin to the top argumentation will accomplish the IC alive and abutting the C1 pin to arena will put the Ic into abeyance mode.
Notes.
- The power supply voltage can be between 2.5 to 6.5V DC.
- For the circuit shown here, the supply voltage must be 3.6 V DC.
- Powering the circuit from a battery is the better option because it reduces noise.
- If you are using a DC power supply, then it must be well regulated and filtered.
- Audio inputs have to be connected with respect to the ground.
