The most capable of beating domestic chip sites, the latest kick-off information received, share with you, welcome to post your opinions and suggestions~

Kicked product: TPA1286
of SiRuiPu. Reason for kicking: Gain multiple can only reach 1000 times.
Recommended alternative product model: COS620ARZ

I checked COS620ARZ, which is a 36V precision instrument amplifier from Cosun. From the gain multiplier alone, COS62 reaches 10000, one more zero than TPA1286. When using amplifiers, what other parameters do forum friends care about? Which of these parameters is better between the two products? I look forward to your comments, suggestions and discussions. You are also welcome to vote for the products you support~

From the parameters, they are basically the same. It depends on whose parameters are more fake. From the test parameters, TPA1286 is better.

The gain bandwidth product, error, etc. are compared, and SiRuiPu is more detailed.

Where can I view the test parameters?
