technical data 2011, january, rev. 0 2 dual operational amplifiers the il4558 is dual general purpose operational amplifiers. the high co mmon - mode input voltage range and the absence of latch - up make these amplifiers ideal for voltage follower application. the devices are short circuit protected and the internal frequency compensation ensures stability without external components. featu re ? short circuit protection ? wide common - mode and differential ranges ? no frequency compensation required ? low power consumption ? no latch - up ? 3 mhz unity gain bandwidth guaranteed ? gain and phase match between amplifiers ? possible to exchange the position of pin 9 for pin1 because of pin connection being symmetric(il4558s only) ordering information il4558n plastic il4558d soic il4558s - 9 sip - 9 il4558s sip - 8 t a = - 40 to 85 c for all packages . il4558 block diagram pin 4 = gnd (v - ) pin 8 = v cc (v+) pin assignment
