| Order this document by LM324/D LM324, LM324A, LM224, LM2902, Quad Low Power Operational Amplifiers The LM324 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. * Short Circuited Protected Outputs LM2902V QUAD DIFFERENTIAL INPUT OPERATIONAL AMPLIFIERS SEMICONDUCTOR TECHNICAL DATA * * * * * * * * True Differential Input Stage Single Supply Operation: 3.0 V to 32 V Low Input Bias Currents: 100 nA Maximum (LM324A) Four Amplifiers Per Package Internally Compensated Common Mode Range Extends to Negative Supply Industry Standard Pinouts ESD Clamps on the Inputs Increase Ruggedness without Affecting Device Operation 14 1 14 1 N SUFFIX PLASTIC PACKAGE CASE 646 (LM224, LM324, LM2902 Only) D SUFFIX PLASTIC PACKAGE CASE 751A (SO-14) PIN CONNECTIONS Out 1 Inputs 1 1 2 14 Out 4 Inputs 4 MAXIMUM RATINGS (TA = + 25C, unless otherwise noted.)

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 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 single supply operation, without saturating either the input devices or the differential to single-ended converter. The second stage consists of a standard current source load amplifier stage. Large Signal Voltage Follower Response VCC = 15 Vdc RL = 2.0 k TA = 25C 1.0 V/DIV 5.0 s/DIV Each amplifier is biased from an internal-voltage regulator which has a low temperature coefficient thus giving each amplifier good temperature characteristics as well as excellent power supply rejection.
