Njm2114 vs ne5532 datasheet

I'm playing around with some simple headphone amps ( again ) with NE5532 vs. OPA2134 OP amps. I've studied around in different forums and found information about differences between the resistor value going to ground. For one of the OP amp it's optimal with 1k and for the other one it's 2k.

用njm2114来替换5532应该是一个不错的选择,不过国内应用较多的是ne5532,njm5532也不多见,njm2114的国内使用报告更是未见,这里把这个似乎有点老的运放推出来,希望起到抛砖引玉的作用。

Jul 22, 2019 · This Low pass filter circuit is working Based on the op-amp ic NE5532. It is a dual op-amp integrated circuit. which will provide a high-quality audio signal. So in this article, I’m going to share some ideas about the circuit and its PCB. NE5532 dual operational amplifier, datasheet, PDF. The NE5532 is a internally compensated dual low noise OP-AMP. The high small signal and power bandwidth provides superior performance in high quality AMP, all control circuits, and telephone applications. MC4558 4 Typical Performance Characteristics Figure 1. Burst Noise vs Source Resistance Figure 2. RMS Noise vs Source Resistance Figure 3. Output Noise vs Source Resistance Figure 4.Texas Instruments NE5532 Series Operational Amplifiers - Op Amps are available at Mouser Electronics. Mouser offers inventory, pricing, & datasheets for Texas Instruments NE5532 Series Operational Amplifiers - Op Amps.

For sure they are best known and are well setup for use as audio drivers, but from a Texas Instruments LM386 datasheet... 8.4 Device Functional Mode As this is an Op Amp it can be used in different configurations to fit in several applications. The internal gain setting resistor allows the LM386 to be used in a very low part count system.The NE5532, being a BJT opamp suffers from low input impedance, again the OP275 having JFET inputs has very high input impedance regardless of the closed-loop gain. The fact that the NE5532 data sheet doesn't even list THD means that it's not specifically and designed for low THD. The OP275 is on the order of 0.006% THD+N.
