MC3303 MC3403 - MC3503 ® LOW POWER QUAD BIPOLAR OPERATIONAL AMPLIFIERS .. .. .. . SHORT-CIRCUIT PROTECTED OUTPUTS CLASS AB OUTPUT STAGE FOR MINIMAL CROSSOVER DISTORTION SINGLE SUPPLY OPERATION : + 3 V TO + 36V DUAL SUPPLIES : ±1.5V TO ±18V LOW INPUT BIAS CURRENT : 500nA MAX INTERNALLY COMPENSATED SIMILAR PERFORMANCE TO POPULAR UA741 N DIP14 (Plastic Package) P TSSOP14 (Thin Shrink Small Outline Package) DESCRIPTION The MC3403 is a low-cost, quad operational amplifier with true differential inputs. The device has electrical characteristics similar to the popular UA741. 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 volts or as high as 36 volts with quiescent currents about one third of those associated with the UA741 (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.

For supply voltages less than ±15V, the absolute maximum input voltage is equal to the supply voltage. 2. Any of the amplifier outputs can be shorted to ground indefinitely ; however more than one should not be simultaneously shorted as the maximum junction temperature will be exceeded.

The first stage of each consists of differential input devices 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 8pF) can be employed, thus saving chip area. ground, in single supply operation, without saturation either the input devices or the differential to single-ended converter. The transconductance reduction is accomplished by splitting the collectors of Q24 and Q22. Another feature of this input stage is that the input commonmode range can include the negative supply of 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. 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 operations. This is possible because class AB operation is utilized. TYPICAL PERFORMANCE CURVES 20µs/div.
