Hello Chenxin,
I do find an OPA4243 listing which is for a quad operational amplifier, but I don't find one for an OPA243. Regardless, if you find an operational amplifier that you want to use and it has offset control pins, most often those pins can…
The OPA145 also looks like a good choice, this file has not been recently updated so the OPA196 is not in yet, and the pricing is out of date.
