Sadly, all the decent.

Reading through your articles I see you’ve chosen the and the as an opamp and datasheet. The article was another late night “rush job”. Have you considered testing several of the same op amp to see production irregularities? The datasheets are usually fairly clear on this.

The dScope was eatasheet directly to the output pin of the op amp being tested the NJM output stage is not included. What are the effects of reducing the isolation resistors to.

Luckily process advancements have provided alternatives to the Difet process and there are now opamps with comparable input bias specs at a fraction of the cost see OPA My main reason for choosing the and were for the much lower current usage. Previous 1 2 Anonymous July 29, at 7: But of course this is a logical fallacy appeal to authority to some extent so Datashret was wondering what you think.

The JRC is stable in the gain stage of the O2 at 2. For the gain stage the final list llm4580 out to: Have you looked on eBay? But, op amps have become so good they can easily approach or even better that.

Drive Capability — To keep Johnson noise low, the op amp should have low distortion into a 1K load. Meares and Charles E. There can be trade offs involved. I can only disagree with one thing: NwAvGuy April 2, at 9: Or it might be borderline unstable with ultrasonic ringing or even oscillation. That’s how my gear is supposed to sound if the manufacture hadn’t used that cheap crappy op amp! Some of the differences heard could be high frequency instability.

dataasheet But a single stage amp, like the Mini3 or a Cmoy, may not. For the output stage it was no contest, the NJM killed everything else. Pardon the Anon status, I’m browsing over a public terminal and the usual cautiousness applies The is the corner stone of nearly all high-end professional audio gear which means most of your music has already been well steeped in goodness. Kanwar August 19, at 5: Like many things in audio it can be a delicate compromise say in an output stage with unknown external loads, or in a gain stage with two different gain options.


NwAvGuy March 5, at 5: But the O2 solves these issues in other ways so FETs are generally more of a liability if accuracy is the goal. I’ve met and talked with one of National Semi’s former audio application engineers about this very issue and his view was it’s much more a problem with poorly designed op amps or op amps being used in the wrong application.

In reality, in most headphone gear, there are lots of op amps that will perform nearly identically as long as they’re used correctly. Since lm450 is project is aimed for portability and low power consumption, the less current it draws, the better.

NE will excel here. But the new fast part is unhappy in a PC board and circuit designed for a much slower part.

Mouser doesn’t sell National Semi op amps. Steve Davies January 31, at 3: In a low gain application, the amp might still show ringing on square waves due to the phase margin becoming small.
