Hi Kevin,

TSX561ILT seems like an auto qualified part from ST. Does this part need to be Q1 grade in your application? TLV1701-Q1 and TLV2372-Q1 (dual channel) are good parts to replace with.

OPA2990 is better in performance than TLV1701-Q1 and TLV2372-Q1 and TSX561ILT. The commercial version is available now and the automotive version will RTM in 4Q this year. If the need is the automotive qualified part I would evaluate electrical performance with the commercial version of OPA2990 and replace it with the Q1 version at the end of the year.

Regards,

Sanjeev

Dear Sanjeev,

Thanks for the promptly reply.

Seems like it is not AEC-Q100 device and one channel.

Will you suggest OPA990, or you have other suggestions?

Hi Kevin,

TSX561ILT has RRIO capability along with low input offset voltage, so I recommend OPA990. OPA990 (single channel) will RTM this October, again evaluation can be done with dual channel and replace with a single channel in October.

If the need is rather urgent I would recommend TLV170 and OPA170.

Regards,

Sanjeev

Looks like the ST part is only 16V, 1MHz, surely there is a closer cross thanthe OPA990
