Could you recommend a replacement chip for PGA280? [Copy link]

The company's purchasing department said that the price of PGA280 has skyrocketed and it is still out of stock. Can you recommend an alternative model that does not require circuit modification?
The specific model is: PGA280AIPW

There are many types of instrumentation amplifiers, and they are highly interchangeable, but the current market situation is hard to say. You should contact the manufacturer or a formal authorized agent. In addition to the PGA series of instrumentation amplifiers, TI also has the INA series. You can find them on TI's official website. In addition, ADI also has many, and domestic Shengbang Micro may also have them. The replacement principle should be based on the specific design, rather than looking for full compatibility. The choice of the two can be greatly different.

Yes, there are many replaceable chips, but I have never found a replaceable chip without changing the circuit. I also did not find a pintopin on the TI official website, so I tried to come to the forum to see if anyone knows.
