3 9 - r ev.1. 0 http://www.elm-tech.com elm852 xa common mode input voltage range is fixed under the condition of cmrr4 5db; elm852xa is able to accept the input above its specification if the degradation of cmrr is not considered. even if the input voltage exceeds either positive or negative power voltage, troubles such as reverse of output will not occur. as maximum absolute rating, the input voltage is possible within (vss -0.3)v to (vdd +0.3)v . 1) common mode input voltage range n ote when op-amp circuit is used with feedback resistor, oscillation may happen i n the circuit with loop-gain like unity gain follower. a) when large feedback resistance is used, the phase margin is decreased by its combination with the parasitic capacitance o f the input part of op-amp. in this situation, please connect small capacitor in parallel with feedback resistor as shown in fig -1 . b) f or capacitive load, external resistor in series connection will be effective as shown in fig -2. ( rl = 300 to 500 ) c) being used as an unity gain follow, elm852xa is able to drive capacitive load of 100pf directly without oscillation. 2) operation from single power source elm852x a is designed to be most suitable for single power source; therefore, elm852xa is able to share power supply with logic circuit one. meanwhile, elm852xa can also operate from double power sources. to protect power supplies of elm852xa 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 elm852x a cmos operational amplifier symbol mark content a, b 5 d elm852ba (sot-25) > 3 elm852ca (sc-70-5) c 0 to 9 and a to z (i, o, x ex cepted .) lot no. d 0 to 9 and a to z (i, o, x ex cepted .) lot no. marking sot - 25 s c -70- 5
