50 of them, to be exact. In today's world, that's a true deal. And they all appear to be in good working order.
No, an AMP with rail-to-rail output is most likely what you're looking for. br>This is a general-purpose application.
There are 50 pieces in this package. Before I bought this, I had the same question.

Excellent called quality at a great price. I've only used a few so far, and they've all worked flawlessly to my knowledge. And I'd be the first to know. I'm an a**hole who bought these to throw out the third-floor apartment windows at little kids on their way to school in the mornings, as if they were gullible suckers who believe they're laying the foundations for the rest of their lives. They'd be digging a giant hole in their back yard to hide silently in until death and stockpiling Vaseline and hemmorhoid pillows if they knew what was in store for them after graduation.
I needed these for my senior project, and now I have an additional 46!.
Amplifier with two operational amplifiers (opamps). Worked perfectly in my over voltage cutoff for a 12VDC project, as well as low voltage for a 3. In these projects, a simple comparator was used. When used as a comparator, the hi output will be around 1. 5 volts less than the supply voltage, which is in line with the device's specifications.
After receiving a batch of 741 op amps that were dead (from a different seller), I made sure to test these as soon as they arrived. I was ecstatic to learn that the product (which had been delivered quickly in the midst of a global crisis) had passed all of the tests. I tested eight of them at random for basic functionality, and they all passed. I was content at that point. br>br>In the meantime, these are very handy op amps, designed for single rail supply, two in a package, and low voltage operation. It's extremely useful to have on hand. All in all, a perfect score.
For input offset voltage testing, I tested 20 of a batch of 50. All of them were able to meet the /- criterion. 5mV specification, and the majority of them were in the /- range. At least 2 millivolts (mV). For most tasks, I'm very happy with these unbranded ones, which are half the price of Digikey or Mouser.
Despite the fact that I have only used/tested about half of them, those that I have used have all performed admirably. The packaging was a little underwhelming at first, but it appears to have served its purpose well. I used a dozen or so of the op amps to make line-following add-ons for some small robots, and another dozen or so for some water clarity testing I was doing. The op amps are ideal for use with CdS cells and photodiodes, which is exactly what I needed them for. I am very pleased with them for the price.
This is a fantastic deal, and it's even easier to get through Amazon Prime. br>These are fantastic little ICs, and they're a great value for the money. br>Shipped quickly.
I needed some op amps quickly, and the local electronics stores had long since closed their doors, and I didn't want to pay $8 shipping on a few dollars' worth of parts from an electronics distributor. The next day, these arrived, and the first one I set up worked perfectly. No bent pins and well-packaged in foam. For 50 pieces delivered the next day, the price is very reasonable.
