MOTOROLA SEMICONDUCTOR TECHNICAL DATA High Slew Rate, Wide Bandwidth, Single Supply Operational Amplifiers Quality bipolar fabrication with innovative design concepts are employed for the MC33071/72/74, MC34071/72/74, MC35071/72/74 series of monolithic operational amplifiers. This series of operational amplifiers offer 4.5 MHz of gain bandwidth product, 13 V/us slew rate and fast setting time without the use of JFET device technology. Although this series can be operated from split supplies, itis particularly suited for single supply operation, since the common mode input voltage range includes ground potential (VEE). With A Darlington input stage, this series exhibits high input resistance, low input offset voltage and high gain. The all NPN output stage, characterized by no deadband crossover distortion and large output voltage swing, provides high capacitance drive capability, excellent phase and gain margins, low open-loop high frequency output impedance and symmetrical source/sink AC frequency response. The MC3307 1/72/74, MC3407 1/72/73, MC3507 1/72/74 series of devices are available in standard or prime performance (A Suffix) grades and are specified over the commercial, industrial/vehicular or military temperature ranges. The complete series of single, dual and quad operational amplifiers are available in the plastic, ceramic DIP and SOIC surface mount packages.

Thus for a given supply voltage, unprecedented peak-to-peak output voltage swing is possible as indicated by the output swing specifications. If the load resistance is referenced to Vcc instead of ground for single supply applications, the maximum possible output swing can be achieved for a given supply voltage. For light load currents, the load resistance will pull the output to Voc during the positive swing and the output will pull the load resistance near ground during the negative swing. The load resistance value should be much less than that of the feedback resistance to maximize pull up capability. Because the PNP output emitter-follower transistor has been eliminated, the MC34071 series offers a20 mA minimum current sink capability, typically to an output voltage of (VEE +1.8 V). In single supply applications the output can directly source or sink base current from a common emitter NPN transistor for fast high current switching applications. In addition, the all NPN transistor output stage is inherently fast, contributing to the bipolar amplifiers high gain bandwidth product and fast settling capability. The associated high frequency low output impedance (30 Q typ @ 1.0 MHz) allows capacitive drive capability from 0 pF to 10,000 pF without oscillation in the unity closed-loop gain configuration. The 60 phase margin and 12 dB gain margin as well as the general gain and phase characteristics are virtually independent of the source/sink output swing conditions. This allows easier system phase compensation, since output swing will not be a phase consideration. The high frequency characteristics of the MC34071 series also allow excellent high frequency active filter capability, especially for low voltage single supply applications. Although the single supply specifications is defined at 5.0 V, these amplifiers are functional to 3.0 V @ 25C although slight changes in parametrics such as bandwidth, slew rate, and DC gain may occur. If power to this integrated circuit is applied in reverse polarity or if the IC is installed backwards in a socket, large unlimited current surges will occur through the device that may result in device destruction. Special static precautions are not necessary for these bipolar amplifiers since there are no MOS transistors on the die. As usual with most high frequency amplifiers, proper lead dress, component placement, and PC board layout should be exercised for optimum frequency performance. For example, long unshielded input or output leads may result in unwanted input-output coupling. In order to preserve the relatively low input capacitance associated with these amplifiers, resistors connected to the inputs should be immediately adjacent to the input pin to minimize additional stray input capacitance. This not only minimizes the input pole for optimum frequency response, but also minimizes extraneous pick up at this node. Supply decoupling with adequate capacitance immediately adjacent to the supply pin is also important, particularly over temperature, since many types of decoupling capacitors exhibit great impedance changes over temperature. The output of any one amplifier is current limited and thus protected from a direct short to ground. However, under such conditions, it is important not to allow the device to exceed the maximum junction temperature rating. Typically for +15 V Supplies, any one output can be shorted continuously to ground without exceeding the maximum temperature rating.
