[PAM8403 Amplifier Board]
Description: 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 4 8 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 hine 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.
[PAM8403 Amplifier Board Micro USB]
The motherboard adopts PAM8403 typical circuit design, adopts MICRO USB power supply (reserved wire bonding interface), which is very convenient to use universal mobile phone charger for power supply. The resistor container part adopts standardized SMT process, and the design is simple and stable. The interface is Bluetooth audio receiving module, which can be easily DIY small. The Bluetooth speaker board can pick up 8 ohm 4 ohm small speakers for all frequency speakers or full range small speakers. Specification: Power supply voltage: DC 3.4V-5V Output power: 3.0W x 2
[PAM8403 Amplifier Board Red]
1. Power supply: DC 2.5-5.5 V. 2. Output power: 3W + 3W (4). 3. SNR: 90dB. 4. Efficiency: > 90%. 5. Size: 15.5×24 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!
