Product Description
LM1875T is a well-known high-performance audio power amplifier integrated circuit, the maximum output power can reach 30W, the sound is mellow, the noise and distortion are quite low, and the protection function is relatively complete, and the performance is stable. Once the LM1875T was launched with rave reviews, it quickly became a standard configuration for small and medium power audio amplifiers and high-fidelity active speaker amplifier circuits. This IC is known to audiophiles, and no one knows it. Looking back more than ten years ago, countless audiophiles were fascinated and fascinated by it. Despite the rapid development of audio technology over the years, this IC has outstanding performance, sound quality, Excellent, still widely used, enduring.
Feature
1, Using the new original LM1875T. 2. The main circuit of electrolytic capacitor adopts famous brand, the capacity of main filter capacitor reaches 2×4700UF/35V, and 25A rectifier flat bridge is used to ensure strong and continuous power support. 3. The resistor adopts five-ring metal film resistor with an accuracy of ±1%, which ensures a good signal-to-noise ratio of the whole machine. 4. The PCB adopts 1.6mm thick FR4 double-sided sheet, 2.0 oz copper thickness, and full tin spraying process to ensure good passing performance of large and small currents. Top-notch PCB quality. 5. The biggest feature of this board is the use of the current advanced C1237 BTL speaker protection circuit, which effectively eliminates the impact sound of opening and closing and the DC output protection function, making your speaker safer. 6. The wiring layout of the entire circuit board is quite rigorous and reasonable, and the overall PCB wiring adopts a large-area copper coating method. The power amplifier board works stably and reliably, with moderate output power; the sound is mellow and mellow, the low frequency is stable and powerful, the signal-to-noise ratio is quite good, and the dynamic range is wide; the details are clear, the transient response is excellent, and it can play all kinds of music. It has a very good performance in the playback environment
