Special internal output processing circuit, eliminating the conventional LC network, EMI values ??lower than the LC!
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.
Super mini digital amplifier board, new high efficiency digital amplifier, the input 5V obtain [3 x 2] 6W of power,
ultra-thin board that is very easy to put into a small plastic box or other device in the slot, such as to create
MP3 / 4 or external speakers and other small laptop, as you imagine, is recommended to take the USB power supply with a single 5V or lithium.
1. The power of positive and negative can not be reversed, the 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!
