在音频电路中需要性能十分优良的功率放大集成电路,经常规定瞬态互调失真指标来鉴定放大器品质,而且选用一块优良的集成电路还可以使产品的研发周期缩短,因此具有很高的使用价值和经济效益。TDA2030就符合音频电路的需求。在音频电路中大功率集成块由于所用电源电压高、输出电流大,在使用中稍有不慎往往致使损坏,而TDA2030具有输出功率大,保护性能以较完善的特点。在解决方案中为使它能达到符合我们所需要的效果,在设计时不能超出极限参数所要求的条件,通过论述TDA2030的特点、TDA2030的极限参数及单电源供电音频放大电路的应用电路分析让读者了解TDA2030在音频电路中的使用。
In the audio circuit needs very good performance of the power amplifier IC, often stipulates transient intermodulation distortion index to identify the amplifier quality, and use a good integrated circuit can also make the product development cycle is shortened, so it has high value And economic benefits. TDA2030 to meet the needs of audio circuits. In the audio circuit in the high-power block due to the use of high power supply voltage, the output current, the use of a little carelessness often cause damage, and TDA2030 has a large output power, the protection of the more perfect features. In the solution to make it meet the effect we need, we can not exceed the requirements of the limit parameters in the design, by discussing the characteristics of TDA2030, TDA2030 limit parameters and application of single-supply audio amplifier circuit analysis The reader understands the use of the TDA2030 in audio circuits.
