LM324 Low Power Quad Op-Amp IC DIP-14

10.00

The LM324IC series are low?cost, quad operational amplifiers with true differential inputs. 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 32 V with quiescent currents about one?fifth of those associated with the MC1741 (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.

The LM324 series is made using four internally compensated, two?stage operational amplifiers. The first stage of each consists of differential input devices Q20 and Q18 with input buffer transistors Q21 and Q17 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 the chip area. The transconductance reduction is accomplished by splitting the collectors of Q20 and Q18. Another feature of this input stage is that the input common-mode range can include the negative supply or ground, in a single-supply operation, without saturating either the input
devices or the differential to the single?ended converter. The second stage consists of a standard current source load amplifier stage.
