6, stmicroelectronics tl072, compared with other brands, more cost-effective, better performance, general audio like to use semiconductor company tl072, the input resistance is relatively large, itThe amplifier chip , and the NE5532N is a similar product model from ON (ON) and PHILIPS (Philips), the index, pin arrangement and package shape size are the same, and can be replaced by each other. Op amp is short for operational amplifier. In the actual circuit, the feedback network is usually combined to form some functional module.
NE5532 is a high performance low noise dual operational amplifier (referred to as dual operational amplifier) integrated circuit. The same structure as many standard operational amplifiers, can be universal, but it has better noise performance, excellent output drive ability and quite highSmall signal bandwidth, power supply voltage range, etc. The ne5532 is therefore ideal for use in high quality and professional audio equipment as a channel pre-amplifier, or as a drive pre-amplifier.
NE5532P is a dual-op amp integrated circuit chip belonging to the precision operational amplifier family. It has the characteristics of low noise, low distortion, high bandwidth and low power consumption, which is suitable for audio amplification and other applications requiring high performance computing amplification. The NE5532P's internal circuitry uses the low noise amplifier chip advanced process design to provide excellent audio performanceAnd stability.
First of all, NE5532 is a dual op amp, so the first question does not need to be answered.
NE5532 is an ordinary audio op amp, the sound quality is not very good. If used for hi-fi, it is recommended that the low noise amplifier chip you use the LM4562, which has a wide operating voltage range and high accuracy. The LM4562 is a high-fidelity dual-op amplifier launched by National Semiconductor in recent years, with ultra-small distortion, only 0.00003% of the total harmonic distortion and noise (THD N), in other words, this operation is amplifiedThe distortion is almost negligible.
Common low-power operation amplifier: LM32LM358. Commonly used high impedance operational amplifier: TL08TL07CA3140. Commonly used precision operational amplifier: OP0OP2ICL7650. Op amp is short for operational amplifier. In the actual circuit, the feedback network is usually combined to form some functional module. Because of its early application in analog computers to implement mathematical operations, it was named "operational amplifier", and this name has continued to this day.
General-purpose operational amplifier chips This class of chips has a wide gain bandwidth and low noise characteristics and is suitable for a variety of general-purpose amplification applications. They have good performance and economy, and are widely used in audio, sensor amplification and signal conditioning circuits. Common general-purpose op amp chips are LM35LM324 and so on.
