Tremendous mini digital amplifier board, ultra-thin , will be very handy to put within the hole of small plastic packing containers or different gadgets. It might probably get hold of most energy output at a decrease voltage. Constructed-in standby digital change, high-gain buffer amplifier, quick circuit safety. It’s good for MP3/MP4/pocket book.
Description:
New environment friendly digital amplifier chip
Particular inside output processing circuit
Eliminating the traditional LC community
Utilizing EMI

Be aware:
Energy optimistic and unfavourable cannot be reversed, the provision voltage cannot exceed 5.5V, these two violations would have led IC harm. On-chip high-gain buffer cannot be altered to to board any element parameters, doesn’t meet the parameters will lead to IC harm. Enter line attempt to use shielded line, you’ll be able to play an anti-jamming impact, eradicate muddle present sound.
Output for cmos tube BTL driver, the unfavourable terminal of the left and proper audio system cannot be collectively, that the 4 traces connecting to the speaker is totally impartial, and doesn’t enable whole entry!
Bundle consists of:
1 x Digital Amplifier Board
New environment friendly digital amplifier chip
Particular inside output processing circuit
Utilizing EMI
Eliminating the traditional LC community
