MC4863PD pdf datasheet

Description

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.

Features

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

Description

The D2627 is 800V, 6A, NPN Triple Diffused Planar Silicon Transistor.

The NPN transistor is used to amplify or switch electronic signals and is widely used in many electronic circuits. It works by controlling the current flow between the collector and emitter terminals through the base terminal.

When a small current is applied to the base, it controls a much larger current between the collector and emitter, making the NPN transistor an effective amplifier or switch.

Characteristics of NPN Transistors:

1. Bipolar Junction: NPN transistors are bipolar junction transistors (BJT), meaning they have a structure consisting of three regions of alternating P-type and N-type semiconductors.

2. Current Amplification: NPN transistors are designed to amplify electrical current, and can be used in a wide range of electronic applications such as amplifiers, switches, and oscillators.

 

Features

• High speed.

• High breakdown voltage(VCBO=1500V).

• High reliability(Adoption of HVP process).

• Adoption of MBIT process.

• On-chip damper diode
