XD-08 super mini digital amplifier board a small USB-powered power amplifier board 3W stereoSuper mini digital amplifier board, get 10 years new and efficient digital amplifier, 5V power input, ultra-thin board [3 x 2] 6W can be very handy gap into small plastic boxes or other equipment inside, such as to create MP3 / 4 or small laptop external speakers, etc., any of you imagine the power of suggestion to take USB powered with a single 5V or lithium. Advantages:a 10-year high efficiency digital amplifier chip, special internal output processing circuitry, eliminating the conventional LC network, lower than the EMI with the LC value! Maximum power output at a lower voltage, super-power, internal electronic switch stand, built-in high-gain buffer amplifier built in short circuit protection. Power: 3.6 to 5.5V, single-cell lithium battery or USB-powered appropriate, also be four 1.2V batteries, power transformers must add 5V regulator circuit chip will burn more than 5.5V.Parameters:Power supply: DC (DC): 3.6v-5.5VOutput power: 3W +3 W (4 ohms)SNR: 90dBefficiency:> 90%Size: 24 * 15.5 * mm positioning hole size: 20mm aperture spacing: 2mm Note : 1: can not reverse the positive and negative power supply voltage must not exceed 5.5V, these two violations could result in IC damage. 2: On-chip high-gain buffer, the board can not change any component parameters do not meet the parameters will result in IC damage. 3: Please try to use the line input cable with shielded, can play a role in anti-interference, eliminating clutter current sound. 4: output cmos tube BTL drive mode, the speaker can not be negative about together, that is connected to the speaker four lines are completely independent, does not allow total access!
