Order this document by MC3403/D The MC3403 is a low cost, quad operational amplifier with true differential inputs. The device has electrical characteristics similar to the popular MC1741C. However, the MC3403 has 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 36 V with quiescent currents about one third 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. • • • • • • • • • • • QUAD DIFFERENTIAL INPUT OPERATIONAL AMPLIFIERS SEMICONDUCTOR TECHNICAL DATA Short Circuit Protected Outputs Class AB Output Stage for Minimal Crossover Distortion 14 True Differential Input Stage 1 Single Supply Operation: 3.0 V to 36 V D SUFFIX PLASTIC PACKAGE CASE 751A (SO–14) Split Supply Operation: ±1.5 V to ±18 V Low Input Bias Currents: 500 nA Max Four Amplifiers Per Package Internally Compensated Similar Performance to Popular MC1741C 14 Industry Standard Pinouts 1 P SUFFIX PLASTIC PACKAGE CASE 646 ESD Diodes Added for Increased Ruggedness Single Supply 3.0 V to 36 V VCC Split Supplies VCC 1 1 2 2 3 3 4 4 VEE, Gnd 1.5 V to 18 V PIN CONNECTIONS Out 1 1 2 Inputs 1 VEE 3 Power Supply Voltages Single Supply Split Supplies Symbol Value Unit Vdc VCC VCC, VEE VIDR 36 ±18 ±36 Vdc Input Common Mode Voltage Range (Notes 1, 2) VICR ±18 Vdc Storage Temperature Range Tstg –55 to +125 °C Input Differential Voltage Range (Note 1) Operating Ambient Temperature Range MC3303 MC3403 TA Junction Temperature TJ 5 Inputs 2 6 + –40 to +85 0 to +70 °C NOTES: 1.

The first stage of each consists of differential input device Q24 and Q22 with input buffer transistors Q25 and Q21 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 Q24 and Q22. 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. The output stage is unique because it allows the output to swing to ground in single supply operation and yet does not exhibit any crossover distortion in split supply operation. This is possible because Class AB operation is utilized. 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.
