Hi Sean,

Is the offset voltage range for the room temperature? If so then OPA990 in SOT-23 package will be P-P compatible with NCS21011 SOT package. This will be 1 MHz part. https://www.ti.com/product/OPA990/samplebuy

If the offset voltage is an absolute max (across temp) then OPA991 will fit the bill. http://www.ti.com/product/OPA2991 This will a 4.5 MHz part. The dual-core version of this part is already RTMed. Single-core is in the development phase. can you give me the detail on the end equipment and when will the customer be going to production?

Regards,

Sanjeev
