Описание товара






LM1875 is a decades-old product, why we have to play LM1875 amplifier circuit?
Because it is not airs and graces, not impulsive, not hysterical, not flourishing leaves and withering flowers also, everything is so real and natural. LM1875 has been a classic of audio player for many years, making simple, but mainly warm timbre, charming, and this unit has built in a protection circuit to protect your valued speakers, don’t be worried about damaging them again.
Top version of this board adopted original National Semiconductor LM1875, and supply voltage from AC dual 12V to dual 22V is available. Recommend about AC dual 18V, and then gain of the circuit is about 30 times magnification.
1. Its input ports are vulnerable by the introduction of outside interference to induce hum when this LM1875 PCBA not installed in a chassis and streaking. The correct connection is fitted in a metal chassis and the ground of signal source connect with the chassis, so it lead to a good shielding effect; in addition, the cable that connect potentiometer connection cable also use shielded one, if you do all above, the amplifier will be all silence even when deep night
2. No including heat sink for this amplifier board.
1. Two side Immersion Gold board.
2. PCB size: 80mm X 65mm, LM1875 IC can be laid down for soldering
You can match LM1036 Tone board, then the LM1875 amplifier will get far better effect as the below. And you can also buy the other matched components as below.
