PAM8403 Amplifier Board Class D 2X3W USB Power Audio 4.0 Receiver SOP Module
1. PAM8403 Amplifier Board Green
1.Advanced Micro Devices, volume: 1.85 * 2.11cm
2.Excellent noise suppression in the case is not connected to the input audio, the ear close to the speaker can not hear any noise
3.Two-channel stereo, 5V power supply can output 3W 3 W power, can directly drive 4Ω 8Ω small speaker output power, full of energy, good sound quality.
4.Unique without LC filter Class D digital power board, and can be used directly to the computer's USB powered.
5.Dual-panel wiring, properly solve the crosstalk between the ground potential balance and channel wiring
6.Ultra-miniature design, can easily be placed in the internal space for a variety of digital products, ultra high zoom efficiency.
7.All using the machine for the entire board soldering, hand soldering iron welding quality comparable!
8.Rated working voltage 2.5-5V, limit operating voltage 5.5V.
Note: The left and right channel output of the "negative" can not, and then together, otherwise it will burn the IC and energized speaker (load) connected before. 2. PAM8403 Amplifier Board Blue1. An onboard PAM8403 audio amplifier chip, 3W * 2 Stereo filterless Class-D audio amplifier2, then 2-way onboard 5.08 (mm) pitch 2P terminal, respectively, left and right channel output wiring3, the chips are pin is already leads to facilitate the external device control4, Working voltage: 5V5, board size: 30 (mm) x30 (mm) 3.PAM8403 Amplifier Board Red
This is a mini 2 channels 3w amplifier with PAM8403. It is perfect for MP3/MP4 Notebook. And you could also power the board with 5V USB power supply.
1. Power supply: DC2.5-5.5 V.
2. Output power: 3W 3W (4Ω).
3. SNR: 90dB.
4. Efficiency: > 90% .
5. Size: 15.5 X 24 mm.NOTE:1. Single lithium battery or USB power supply is suitable, also can use four sections of 1.5V battery, if use with the transformer power supply,it must add 5V voltage circuit, more than 6V will burn IC out.
2. and - of power supply can't be reversed, power supply voltage can't be more than 6V, otherwise it will damage the IC.
3. there were high gain buffers, can't change any board device parameters, do not accord with the parameters of the IC will lead to damage.
4. input wire please use shielding wire, can rise anti-interference function, eliminate clutter current sound.
5. output is CMOS BTL drive mode,4 wire is completely independent, don't connect together!
4.PAM8403 Module
Operating voltage: 2.5V-5.5V
Maximum output power: 3W*2(5V 4Ω)
PCB size :
Length: 29mm
Width: 20mm
Overall height after installed is about 16mm.
Note:please make sure the power supply is not more than 5.5V andplease don't do reverse polarity for " " and "-", or else, it will burn the board.
