Hello Evgenii,
Sorry to hear about the difficulties obtaining the TLC27M9I in Russia. Have you checked the TLC27M9 web page to see if you can order samples directly off of it? Have you checked with your local TI distributor about obtaining some samples…
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also looks like a good choice, this file has not been recently updated so the OPA196 is not in yet, and the pricing is out of date.
