? semiconductor components industries, llc, 2001 march, 2001 rev. 1 1 publication order number: mc3458/d mc3458, mc3358 dual, low power operational amplifiers utilizing the circuit designs perfected for the quad operational amplifiers, these dual operational amplifiers feature: low power drain, a common mode input voltage range extending to ground/v ee , and single supply or split supply operation. these amplifiers have several distinct advantages over standard operational amplifier types in single supply applications. they can operate at supply voltages as low as 3.0 v or as high as 36 v with quiescent currents about onefifth of those associated with the mc1741c (on a per amplifier basis). the common mode input range includes the negative supply, thereby eliminating the necessity for external biasing components in many applications. the output voltage range also includes the negative power supply voltage. ? short circuit protected outputs ? true differential input stage ? single supply operation: 3.0 v to 36 v ? low input bias currents ? internally compensated ? common mode range extends to negative supply ? class ab output stage for minimum crossover distortion ? single and split supply operations available ? similar performance to the popular mc1458 device package shipping ordering information mc3358d so8 98 units/rail mc3358dr2 so8 http://onsemi.com 2500 tape & reel pdip8 p1 suffix case 626 1 8 so8 d suffix case 751 1 8 marking diagrams x = 3 or 4 a = assembly location wl, l = wafer lot yy, y = year ww, w = work week mc3358p1 pdip8 50 units/rail pin connections vee/gnd inputs a inputs b output b output a vcc + + 1 2 3 4 8 7 6 5 (top view) mc3458d so8 98 units/rail mc3458dr2 so8 2500 tape & reel mc3458p1 pdip8 50 units/rail 1 8 mc3x58p1 awl yyww alyw 3x58 1 8
