( rl = 300 to 500 ) c) being used as an unity gain follow, ELM824xa is able to drive capacitive load of 100pf directly without oscillation. 2) operation from single power source ELM824x a is designed to be most suitable for single power source; therefore, ELM824xa is able to share power supply with logic circuit one. meanwhile, ELM824xa can also operate from double power sources. to protect power supplies of ELM824xa 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 two amplifiers will consume power even if only one amplifier is used. in order to minimize power consumption by the unused amplifier, elm recommends to connect this amplifier as voltage follower circuit and the input terminal (in+) to vdd . 4) unused amplifier ELM824x a 3.0 a very low power cmos dual operational amp lifier
