if I connect the output of the LTC2057 (+5V,-5V) to the positive input of an ADC, what would be the worst case offset voltage applied to IN+ of the ADC? the offset voltage according to the datasheet would be around (-0.43uV+(Temp-25)*1.29nV), is that right…

if the input to IN+ or IN- are out of the range of VS+ and Vs-, then the output will rail to VS, but is there still any limitation for the input value or time of exposure, to avoid any damage to the OPAMP? 

Hello.

I am designing a circuit using the Ltc2057 with bipolar +/- 15V power supply. My question is, when the op amp enters in shutdown mode, what is the minimum/max output voltage of this op amp...

Best regards,

用到ltc2057hv，+40v供电，但是输出最大只能达到13.3V，是什么原因？谢谢

使用ltc2057Hv，+40v单电源供电，同相放大G=11，输出只能达到13.3V，请问是什么原因？谢谢

Hi,

I have used these component to design a sinusoidal current generator 0-2Arms 50Hz-2kHz.

I need to have a very low offset (DC component), max 300-400uA.

Could you please give me help to low the offset?

Thanks

Best Regards

Hi,

It's not exactly clear from the datasheet if for the external reference case the buffer amplifier still has a gain of 2 as it has in case of using the internal reference(2.5V  for AD5644RBRMZ-5 part and it has a range  from 0-5V).

My system reference…
