Dear sir,

Does TI have a rail-to-rail OPAMP (In or In to V+) that pinout the same as LM321?

Please refer below figure. DBV 5-pin SOT-23

And it need to operate under 12V supply.

Does TI have this solution?? Thank you very much.

Hi CK,
Please check TLV9001, that's available in DBV package. Here is the link to the datasheet: www.ti.com/.../tlv9002.pdf. I hope this helps!

Best Regards,

CK Ho,

TLV2370, OPA743 and OPA191 are few options with high voltage (>12V) supply capability, comparable specs and RRIO. But these are not directly P2P compatible with LM321. You will have to swap your Pin1, Pin3 and Pin 4.

Lets us know if this is a viable solution.

Regard,

Sanjeev

Dear Bala Ravi,

I know TLV9001 is pin compatible. But we need the OP operate under 12V.

TLV9001 only can operate under 5.5V

But still thanks for your reply. Thank you very much.

Dear Sanjeev,

OK, thank you very much.

Now I suggest TLV2371 to customer. I will discuss with them whether they accept to revise layout.

Thanks for your support.
