MC4863PD pdf datasheet


The MC4863PD is a dual bridge-connected audio power amplifier which, when connected to a 5V supply, will deliver 2.2W to a 4Ω load(Note 1) or 2.5W to a 3Ω load(Note 2) with less than 1.0% THD+N. In addition, the headphone input pin allows the amplifiers to operate in single-ended mode to drive stereo headphones.

Boomer audio power amplifiers were designed specifically to provide high quality output power
from a surface mount package while requiring few external components,to simplify audio system
design, it combines dual bridge speaker amplifiers and stereo headphone amplifiers on one chip.


1. Single-ended mode – THD+N 0.5%(max) at 75mW into 32Ω

2. Shutdown current 0.7μA(typ)

3. Stereo headphone amplifier mode

4. “Click and pop” suppression circuitry

5. Unity-gain stable

6. Thermal shutdown protection circuitry

DDA001AG is Power Supply IC Chip. A power supply IC chip, often referred to as a voltage regulator IC or voltage regulator, is a semiconductor device used to control and regulate the voltage supplied to electronic circuits and components. These chips are essential in various electronic devices and systems to ensure a stable and constant voltage supply.

DDA001AG Datasheet, Pinout


1. Linear Voltage Regulators: Linear voltage regulators are used to provide a stable output voltage from a variable or higher input voltage. They are straightforward and efficient but are best suited for low-to-moderate current applications.

2. Switching Voltage Regulators: Switching voltage regulators, also known as DC-DC converters, are more complex but highly efficient. They can step up (boost), step down (buck), or invert the input voltage to produce a regulated output voltage.

3. LDO (Low Dropout) Regulators: LDO regulators are a type of linear regulator that can maintain a stable output voltage even when the input voltage is only slightly higher than the desired output voltage. They are commonly used in battery-powered devices.
