MC34071,2,4,A MC33071,2,4,A 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 series of monolithic operational amplifiers. This series of operational amplifiers offer 4.5 MHz of gain bandwidth product, 13 V/µs slew rate and fast setting time without the use of JFET device technology. Although this series can be operated from split supplies, it is 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 MC33071/72/74, MC34071/72/74 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 plastic DIP, SOIC and TSSOP surface mount packages. • Wide Bandwidth: 4.5 MHz • High Slew Rate: 13 V/µs • Fast Settling Time: 1.1 µs to 0.1% • Wide Single Supply Operation: 3.0 V to 44 V • Wide Input Common Mode Voltage Range: Includes Ground (VEE) • Low Input Offset Voltage: 3.0 mV Maximum (A Suffix) • Large Output Voltage Swing: –14.7 V to +14 V (with ±15 V Supplies) • Large Capacitance Drive Capability: 0 pF to 10,000 pF • Low Total Harmonic Distortion: 0.02% • Excellent Phase Margin: 60° • Excellent Gain Margin: 12 dB • Output Short Circuit Protection • ESD Diodes/Clamps Provide Input Protection for Dual and Quad http://onsemi.com 8 1 8 SO–8 D SUFFIX CASE 751 1 P SUFFIX CASE 626 PIN CONNECTIONS Offset Null 1 Inputs VEE 8 NC 2 – 7 3 + 6 VCC Output 5 Offset Null 4 (Single, Top View) Output 1 1 2 Inputs 1 3 VEE VCC Output 2 8 7 – + 6 – + 4 Inputs 2 5 (Dual, Top View) 14 14 1 SO–14 D SUFFIX CASE 751A 1 P SUFFIX CASE 646 14 1 TSSOP–14 DTB SUFFIX CASE 948G PIN CONNECTIONS Output 1 Inputs 1 1 14 2 13 3 VCC 1 4 – + 4 5 Inputs 2 6 Output 2 – + Inputs 4 12 11 + – 2 3 + – 7 Output 4 VEE 10 9 8 Inputs 3 Output 3 (Quad, Top View) ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 17 of this data sheet.

If one or both inputs exceed the upper common mode voltage limit, the amplifier output is readily predictable and may be in a low or high state depending on the existing input bias conditions. Since the input capacitance associated with the small geometry input device is substantially lower (2.5 pF) than the typical JFET input gate capacitance (5.0 pF), better frequency response for a given input source resistance can be achieved using the MC34071 series of amplifiers. This performance feature becomes evident, for example, in fast settling D–to–A current to voltage conversion applications where the feedback resistance can form an input pole with the input capacitance of the op amp. This input pole creates a 2nd order system with the single pole op amp and is therefore detrimental to its settling time. In this context, lower input capacitance is desirable especially for higher Although the bandwidth, slew rate, and settling time of the MC34071 amplifier series are similar to op amp products utilizing JFET input devices, these amplifiers offer other additional distinct advantages as a result of the PNP transistor differential input stage and an all NPN transistor output stage. Since the input common mode voltage range of this input stage includes the VEE potential, single supply operation is feasible to as low as 3.0 V with the common mode input voltage at ground potential. The input stage also allows differential input voltages up to ±44 V, provided the maximum input voltage range is not exceeded. Specifically, the input voltages must range between VEE and VCC supply voltages as shown by the maximum rating table. In practice, although not recommended, the input voltages can exceed the VCC voltage by approximately 3.0 V and decrease below the VEE voltage by 0.3 V without causing product damage, although output phase reversal may occur. It is also possible to source http://onsemi.com 10 MC34071,2,4,A MC33071,2,4,A 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 amplifier’s high gain bandwidth product and fast settling capability. The associated high frequency low output impedance (30 Ω 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 @ 25°C 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 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. values of feedback resistances (lower current DACs). This input pole can be compensated for by creating a feedback zero with a capacitance across the feedback resistance, if necessary, to reduce overshoot. For 2.0 kΩ of feedback resistance, the MC34071 series can settle to within 1/2 LSB of 8 bits in 1.0 µs, and within 1/2 LSB of 12–bits in 2.2 µs for a 10 V step. In a inverting unity gain fast settling configuration, the symmetrical slew rate is ±13 V/µs. In the classic noninverting unity gain configuration, the output positive slew rate is +10 V/µs, and the corresponding negative slew rate will exceed the positive slew rate as a function of the fall time of the input waveform. Since the bipolar input device matching characteristics are superior to that of JFETs, a low untrimmed maximum offset voltage of 3.0 mV prime and 5.0 mV downgrade can be economically offered with high frequency performance characteristics. This combination is ideal for low cost precision, high speed quad op amp applications. The all NPN output stage, shown in its basic form on the equivalent circuit schematic, offers unique advantages over the more conventional NPN/PNP transistor Class AB output stage. A 10 kΩ load resistance can swing within 1.0 V of the positive rail (VCC), and within 0.3 V of the negative rail (VEE), providing a 28.7 Vpp swing from ±15 V supplies. This large output swing becomes most noticeable at lower supply voltages. The positive swing is limited by the saturation voltage of the current source transistor Q7, and VBE of the NPN pull up transistor Q17, and the voltage drop associated with the short circuit resistance, R7. The negative swing is limited by the saturation voltage of the pull–down transistor Q16, the voltage drop ILR6, and the voltage drop associated with resistance R7, where IL is the sink load current. For small valued sink currents, the above voltage drops are negligible, allowing the negative swing voltage to approach within millivolts of VEE. For large valued sink currents (>5.0 mA), diode D3 clamps the voltage across R6, thus limiting the negative swing to the saturation voltage of Q16, plus the forward diode drop of D3 (≈VEE +1.0 V). 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 VCC 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 a 20 mA http://onsemi.com 11 MC34071,2,4,A MC33071,2,4,A (Typical Single Supply Applications VCC = 5.0 V) Figure 37.
