Amplifier similar to LTC6373

I would ideally like to use the LTC6373 as the buffer amplifier to the ADAQ4003, but it is not available for at least 4 months. Is there an amplifier that is similar? For reference, it needs to be very low noise, differential output, able to be supplied with +/- 15V--programmable gain is not so important but would be nice. Thanks!

Hi Katy1163_AC,

I'm curious to why do you want a buffer amplifier to ADAQ4003. ADAQ4003 has an internal buffer already. Do you have a reference design for this? or could you share your application for this design?

Could you also share what your input range is?

Regards,

Kristine

Hi Kristine,

Thanks for getting back to me! I am using the Eval board for the ADAQ4003 (EVAL-ADAQ4003FMCZ) as an example. On the eval board, there is are 2 buffer options--ADA4898 op amp and AD8251 In amp. My input range is either +/- 5V or +/- 10V (selectable).
