Sergey I.13 November 2021·Show originalTo Moscow, the fee drove 17 days, the track was tracked. The price taking into account the delivery of 161 rubles. Packed in a paper bag, pupyrku and another pupyrku! Even if they jumped on the parcel, the fee would not have been damaged :) sizes 18x15mm. The workmanship is very good, there are no traces of flux. Probably, I'll add a review after the amplifier board test in the case. Who is interested in the details about how it works, and most importantly-does it work at all? -Welcome :)

Description
Imported chip PAM8403, 3W dual channel D digital high power supply, the efficiency of up to 90%. Ultra thin design, can be convenient to install suitable for the use of DIY modification, input 5V horn 4 ohm impedance output maximum 2X3W power.10 years of new high efficient digital power amplifier chip, the internal special output processing circuit, the abolition of the traditional LC network, lower than the EMI value of LC! Get maximum power output at lower voltage, super power saving, built in standby electronic switch, built-in high gain buffer amplifier, built in short circuit protection.
Power supply voltage: 2.5~5.5VDC
Module size: 18.5 mm long, 15.5 mm wide and 2.8 mm thick.
Power supply recommendations of a single rechargeable lithium battery or USB5V power supply, but also can be used in the three section of the 1.5V battery or four 1.2V rechargeable battery powered. Transformers must add 5V voltage regulator circuit, voltage regulator circuit and voltage ripple over 5.5V chip will burn.
Power supply and negative pole can not be connected to the power supply voltage can not exceed 5.5V, otherwise it will burn IC damage. Do not change any component parameters on the board, do not meet the parameters will lead to IC damage.
Audio input line as far as possible with a shielded wire, you can play the role of anti interference, eliminating clutter current sound. Output for the BTL tube CMOS drive mode, the negative pole of the left and right speakers can not be connected together, that is, the 4 lines of the speaker is completely independent, does not allow a common ground, otherwise it will burn IC damage. Turn on the speaker before switching on the power supply, otherwise it is easy to cause damage to the chip;
Because of the digital volume control module has a lot of gain, so do not let the audio signal input is too large and distortion Application: LCD TV, monitor, notebook computer, portable speakers, portable DVD players, game consoles, mobile phone hands-free phone / etc.
