I was wondering if the ADA4891-1 can be used as a unity gain buffer? I have a unity gain stable amp on my PCA already but for consolidation of parts and for operating temperature range, I would like use an existing amp I have on my board, the ADA4891-1. My input signal is a relatively stable output from a DAC which varies between 0 and +3.3V. You can treat the DAC signal as DC. My other option is to use a new part such as the ADA4622-1 which is unity gain stable and works over -40C to 125C
Your advice would be much appreciated.
