The NJM4556A integrated circuit is a high-gain,high output current dual operational amplifier capable of driving ±70mA into 150Ωloads ( ±10.5V output voltage ),and operating low supply voltage ( V+ / V- =±2V~ ).

2005年11月8日 · There is only so much you can do with a single op amp to get rid of heat. Then you can build better power supplies and use the better op amps to full effect. You will find the 4556 is used in almost every product without an amplifier …

2011年8月19日 · I know that the NJM4556AD works OK in a multiple headphone amp. How about the NJM4558? Its data sheet says nothing about "high current", but it also says nothing about "output current". My goal is to build such an headphone distribution amp. Are there any other options, i.e a multiple pin TO220-ish size.

2011年2月4日 · Okay, if anybody is listening, and has a schematic for a magnetic phono amp using NJM4556's, the only reason to use that IC is for high current for the headphone driver. A modern op amp in a TO220 package with big heat sink is TI OPA453. +-10 to +-40 v power supply, 50 ma drive capability, 7.5 Mhz Ft, 23 v/microsec slew rate.

The NJM4556A integrated circuit is a high-gain,high output current dual operational amplifier capable of driving ±70mA into 150Ωloads ( ±10.5V output voltage ),and operating low supply voltage ( V+ / V- =±2V~ ).

2004年3月16日 · OK, but the 4556 is not a low-current opamp, at 70ma per channel. There are better opamps for sure - even the njm2068 imho, which can sink roughly as much current and is faster, higher bandwidth, and lower noise. On one hand, it's probably better to move amplification to something with a cleaner power supply than a computer.

The 4556 Operational Amplifier (Op Amp) is a versatile electronic component that plays a crucial role in various applications across diverse industries. This article provides an overview of the features and applications of the 4556 Op Amp, offering insights into its …
