I want to use AD8275 for attenuating the output from sensors varying from -10V to +10V, before giving to ADC.
Is AD8275 meant to use only for driving 16 bit successive approximation ADC? Is it possible to use AD8275 for driving 24-bit ADS1220, which is having sigma delta architecture?
Also, Can we use AD8275 without adding op-amp buffer at the input side? In which all system conditions, would you recommend to use input op-amp buffer?
