You can replace NJM2068 by LM4562. NJM4580 requires more care, usually a high-current not-too-fast FET opamp is suitable. To utilize AD8620 requires some knowledge on the circuit. If it is well implemented, non prone to oscillation, with high input impedance and within supply specs, it should work well.

2024年1月2日 · I know the NJM2068 is available. The original NJM2068SD was SIP-9, but from my understanding, the 9th pin was an extra V+ and isn't used in the circuit. Can the current NJM2068 replace it? Pin configuration is different, kinda. The current NJM2068 doesn't have the extra V+ on Pin 1, the rest is the same but moved up a pin.

2019年10月9日 · Yamaha has done much worse, like torturing a poor little OP275 with 390R/220R at the same spot in the A-S700 (hint: it's an OK-ish load driver but well short of an NE5532). If you don't bother its output stage too much, the NJM2068 isn't a bad performer at all (NwAvGuy measurements - Samuel Groner unfortunately skipped this part).

2014年2月4日 · NJM2068 are really quiet .NAD, Tascam, Fostex used them. I don't trust Groner's analysses, measurements and claims. At all! OPA2132 and OPA2228 are really good sounding op-amps.OPA2132 is not identical to OPA2134 " except offset" as Groner claimed.They do sound differently on different type of loads and i'm not a golden ear.

2012年3月22日 · The NJM2068 has a Slew rate of 6V/uSec, the 4558 has 1V slew. Also the Bandwidth has increased from 3 MHz to 27MHz. Want to cut the old pins of the 4558 and solder the new 2068 on the old pins. Want to prevent stray inductances and (oscillations?) by this method. From a supplier in Asia I ordered 50 pieces for $ 28.00.

But some people like a little bite in their soup. BTW, the MKS is polyester, not polypropylene. As for the IC, in this fairly-high source impedance application, you might try a FET-type opamp like a OPA1642. It's a lot more money than a NJM2068 (which is a …
