They have several distinct advantages over standard operational amplifier types in single supply applications. The quad amplifier can operate at supply voltages as low as 3.0 V or as high as 3 V with quiescent currents about onefifth of those associated with the M74 (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.

4 , A, LM4, LM90 IUIT DESIPTION The series is made using four internally compensated, twostage operational amplifiers. The first stage of each consists of differential input devices Q0 and Q8 with input buffer transistors Q and Q7 and the differential to single ended converter Q3 and Q4. The first stage performs not only the first stage gain function but also performs the level shifting and transconductance reduction functions. By reducing the transconductance, a smaller compensation capacitor (only 5.0 pf) can be employed, thus saving chip area. The transconductance reduction is accomplished by splitting the collectors of Q0 and Q8. Another feature of this input stage is that the input common mode range can include the negative supply or ground, in single supply operation, without saturating either the input devices or the differential to singleended converter. The second stage consists of a standard current source load amplifier stage..0 V/DIV Large Signal Voltage Follower esponse 5.0 µs/div = 5 Vdc L =.0 kω TA = 5 Each amplifier is biased from an internalvoltage regulator which has a low temperature coefficient thus giving each amplifier good temperature characteristics as well as excellent power supply rejection.
