IWISTAO HIFI LM1875 Parallel Power Amplifier Board 2x50W Stereo DIY Audio

Model No: WPAB-LM1875T

LM1875T is a well-known high-performance audio power amplifier integrated circuit of the US National Semiconductor (NSC). The maximum output power is up to 30W, the tone is mellow, the noise and distortion are quite low, and the protection function is perfect and the performance is stable.

The LM1875T has received rave reviews and soon became the standard for low- and medium-power audio amplifiers and high-fidelity active speaker amplifiers. This IC is very famous to audiophiles. Recalling that more than a decade ago, countless enthusiasts dumped and fascinated, despite the rapid development of audio technology over the years, this IC is superior in performance and sound quality. Excellent, still widely used today, and enduring.

Features

1. Built-in the new original LM1875T.

2. Its main circuit of electrolytic capacitor adopts brand NOVER one, the main filter capacitor capacity reaches 10000UF/35V*2, and the 25A rectifier flat bridge is used to ensure strong and continuous power support.

3. The resistors use five-ring metal film resistor with ±1% accuracy to ensure a good signal-to-noise ratio.

4. The PCB adopts 1.6mm thick FR4 double-sided sheet, 2.0 oz copper thickness, and the whole process of tin-spraying ensures the good passing performance of large and small currents. First-class PCB quality.

5. Its biggest feature of this board is using advanced C1237 BTL speaker protection circuit currently, which effectively eliminates the impact sound and DC output protection function of the open and shutdown, making your speaker safer.

6. The layout of the entire circuit board is quite rigorous and reasonable. The overall PCB trace is made of large-area copper. The power amplifier board works stably and reliably, the output power is moderate; the sound is mellow and round, the low frequency is steady and powerful, the signal-to-noise ratio is quite excellent, the dynamic range is wide, the details are clear, the transient response is excellent, and all kinds of music are played freely, and the space is not big. Very good performance in the playback environment
