( rl = 300 to 500 ) c) being used as an unity gain follow, ELM822xa is able to drive capacitive load of 100pf directly without oscillation. 2) operation from single power source ELM822x a is designed to be most suitable for single power source; therefore, ELM822xa is able to share power supply with logic circuit one. meanwhile, ELM822xa can also operate from double power sources. to protect power supplies of ELM822xa and logic circuit from noise, please separate wire from power supply and use decouplin g (bypass ) c apacitor. using the capacitor can improve psrr characteristics, especially on 10khz to 100khz or more. 3) feedback a ) fig -1 b ) fig - 2 ELM822x a 1 . 5 a very low power cmos operational amp lifier
