Alternative to LTC2057HV

Question

Hi to all, the LTC2057HV has an excellent offset voltage and a very low offset drift. Is there an alternative available out, but with a higher supply voltlage than 60V? We want to measure very small voltage changes (less than 1mV) but a common mode voltage of 70V. The LTC6090 seems to be a good choice, but is has a quite high voltage drift. I would appreciate if someone has a hint. 
 Kind regards Chris

Hi ChrisWeb , 
 Good day. We'll be looking into this query. Aside from the parameters you have stated, are there other critical parameters in your design such as the bandwidth and slew rate?

Hi ChrisWeb , 
 Good day. You may want to check ADHV4702, a 24 V to 220 V Precision Operational Amplifier with a 2 &micro;V/&deg;C maximum input offset voltage (VOS) drift, a bandwidth of 10 MHz, and an input common-mode voltage range of +/- 107 V. You can check the datasheet here: https://www.analog.com/media/en/technical-documentation/data-sheets/adhv4702-1.pdf . I hope this helps. Thank you.
