在《电子制作》2000年第9期上卢涛给大家介绍用LM386制作OTL功放。LM386还可制作成OCL功放,即没有输出电容的功率放大器。其功率提高了一倍且低频的频响更宽,用它来推动一对3W小音箱,电路简洁效果不错,有兴趣的不妨试试。元件介绍 LM386具有频响宽、功耗低、电压适应范围宽,外接元件少等特点。工作电压为4～16V,当电压为6V
In the “electronic production” in 2000 on the 9th Lu Tao introduced to everyone with LM386 production OTL amplifier. The LM386 can also be made as an OCL amplifier, a power amplifier with no output capacitance. Its power is doubled and the frequency response of the low frequency is wider, use it to promote a pair of 3W small loudspeaker, the circuit is simple and good result, it is interested to try. Components LM386 has a wide frequency response, low power consumption, wide voltage range, fewer external components and so on. Working voltage is 4 ~ 16V, when the voltage is 6V
