20pcs TL072 072 Low Noise JFET Dual Op-Amp Operational Amplifiers IC Chip,DIP-8.

⭐️⭐️⭐️⭐️⭐️ Great Value for DIY Audio Projects I bought this 20-pack of TL072 op-amps for some guitar pedal and audio projects, and they’ve been working perfectly. The chips are clean, consistent, and deliver the low-noise performance you expect from TL072s. I tested several from the batch, and all functioned as they should with no duds. These are great for hobbyists, amp builders, or anyone needing a reliable stock of op-amps at a good price. Having 20 pieces on hand is super convenient when prototyping or swapping into different circuits. ✅ Pros: Excellent value for a bulk pack Genuine, noise-free operation Perfect for audio/electronics DIY work All pieces tested good ⚠️ Cons: No fancy packaging (just anti-static bag), but that’s expected at this price Overall, a solid purchase if you need a dependable supply of TL072s for your projects.

Excellent value and quality, these work great and nice amount to have. Happy with purchase.

These ICs work perfectly for guitar pedals. As the listing title states they are low noise. Also, the price is outstanding!!

If you are looking for extremely low input bias current like you would get with a real GENUINE TL072, then do yourself a favor: LOOK ELSEWHERE! And I really do mean elsewhere. These things are ABSOLUTE JUNK! I don't know what these devices are, but they surely are NOT TL072 devices. A REAL TL072 has an input bias current of 20 pA (data sheet states 20 pA typical, 200 pA maximum; good grief, a portion of the data sheet is even included in the product description!). I was very suspicious because things weren't working correctly, so I did some testing. Some parts have input bias currents of 1-2 nA, and many are in excess of 10 nA. I tested nine, and it's about half and half. After that, I gave up. I measured less than 20 pA on devices from a reputable seller (DigiKey). I paid $6.37 for 10 (64 cents each) at DigiKey. These devices from Amazon are $8.49 for 20 (43 cents each). Of course, I had to pay a shipping charge with DigiKey, but wouldn't you rather have devices that actually work for not much more money? They may work just fine for some projects where you don't need extremely low input bias current, as with a generic run-of-the-mill op-amp circuit (of course, you would then most likely be using a different part anyway). But, still, I find it quite disturbing that these devices are so out of spec. Maybe they are reject TL072s, or maybe they are some other cheap part that was intentionally mislabeled and passed off as a TL072. Who knows. I read a review for another semiconductor device elsewhere on Amazon where the reviewer said that, because of the quality issues (or lack thereof), he was no longer going to buy semiconductors from Amazon sellers, instead going to DigiKey or Mouser. I will most likely be doing the same, especially for critical parts like this one.

Fantastic op amps! They do what they are supposed to do! I've been building guitar pedals

They're ok - not quite real TL072s, but most of the 20 work well.

Neatly packaged and so far chips work as expected.

These worked well for a lightening detector circuit.
