LM837是专为低噪声应用而设计的四运算放大器,具有高速和宽带宽等优点,并具有能够直接驱动600Ω负载能力的新型输出级,几乎可以用它来设计所有的音响设备,如数字音频、图示均衡器、前置放大器和专业音响等设备,本电路在低噪声方面有良好的性能,同时还适用于测试仪器。 LM837为内补偿型,它的引脚与大多数的标准四运算放大器兼容,若将其代替现有的普通四运放,可不作改动或稍加小的改动,就能将原电路的质量提高。该电路采用14脚引出线,有
The LM837 is a quad op amp specifically designed for low noise applications. It features high speed and wide bandwidth, and has a new output stage that can directly drive a 600Ω load. It can be used to design virtually any audio device such as digital audio, Graphic equalizer, preamplifier and professional audio equipment, the circuit has good performance in low noise, but also for test equipment. The LM837 is an internal compensation type. Its pins are compatible with most standard quad op amps. If the LM837 is replaced by an existing normal quad op amp, the quality of the original circuit can be improved without any modification or slight changes . The circuit uses 14-pin leads, there
