LM613 Adjustable Reference General Description The LM613 consists of dual op-amps, dual comparators, and a programmable voltage reference in a 16-pin package. The op-amps out-performs most single-supply op-amps by pro- viding higher speed and bandwidth along with low supply current. This device was specifically designed to lower cost and board space requirements in transducer, test, measure- ment, and data acquisition systems. Combining a stable voltage reference with wide output swing op-amps makes the LM613 ideal for single supply transduc- ers, signal conditioning and bridge driving where large common-mode-signals are common. The voltage reference consists of a reliable band-gap design that maintains low dy- namic output impedance (1Q typical), excellent initial toler- ance (0.6%), and the ability to be programmed from 1.2V to 6.3V via two external resistors. The voltage reference is very stable even when driving large capacitive loads, as are com- monly encountered in CMOS data acquisition systems. As a member of Nationals Super-Block family, the LM613 is a space-saving monolithic alternative to a multi-chip solu- tion, offering a high level of integration without sacrificing performance.

Electrical specifications do not apply when operating the de- vice beyond its rated operating conditions. Note 2: Input voltage above V* is allowed. As long as one input pin voltage remains inside the common-mode range, the comparator will deliver the correct output. Note 3: More accurately, it is excessive current flow, with resulting excess heating, that limits the voltages on all pins. When any pin is pulled a diode drop below V-, a parasitic NPN transistor turns ON. No latch-up will occur as long as the current through that pin remains below the Maximum Rating. Operation is undefined and unpredictable when any parasitic diode or transistor is conducting. Note 4: Simultaneous short-circuit of multiple comparators while using high supply voltages may force junction temperature above maximum, and thus should not be continuous. Note 5: Junction temperature may be calculated using Ty = Ta + Pp 84. The given thermal resistance is worst-case for packages in sockets in still air. For packages soldered to copper-clad board with dissipation from one comparator or reference output transistor, nominal 6, is 90C/W for the N package, and 135C/W for the WM package. Note 6: Human body model, 100 pF discharged through a 1.5 kQ resistor. Note 7: Typical values in standard typeface are for Ty = 25C; values in bold face type apply for the full operating temperature range. These values represent the most likely parametric norm. Note 8: All limits are guaranteed at room temperature (standard type face) or at operating temperature extremes (bold type face). Note 9: Slew rate is measured with the op amp in a voltage follower configuration. For rising slew rate, the input voltage is driven from 5V to 25V, and the output voltage transition is sampled at 10V and @ 20V. For falling slew rate, the input voltage is driven from 25V to 5V, and the output voltage transition is sampled at 20V and 10V. Note 10: Vp is the Cathode-to-feedback voltage, nominally 1.244V. Note 11: Average reference drift is calculated from the measurement of the reference voltage at 25C and at the temperature extremes. The drift, in ppm/C, is 10*AVa/(Vapso]*ATy), where AVp is the lowest value subtracted from the highest, Vpjos:c] is the value at 25C, and ATy is the temperature range. This parameter is guaranteed by design and sample testing. Note 12: Hysteresis is the change in Vp caused by a change in Ty, after the reference has been dehysterized. To dehysterize the reference; that is minimize the hysteresis to the typical value, its junction temperature should be cycled in the following pattern, spiraling in toward 25C: 25C, 85C, -40C, 70C, 0C, 25C. Note 13: Low contact resistance is required for accurate measurement. Note 14: A military RETS 613AMX electrical test specification is available on request.

With current I, flowing in the forward direction there is the familiar diode transfer func- tion. |, flowing in the reverse direction forces the reference voltage to be developed from cathode to anode. The cath- ode may swing from a diode drop below V to the reference voltage or to the avalanche voltage of the parallel protection diode, nominally 7V.

Voltage Associated with Reference (current source I, is external) The reference equivalent circuit reveals how V, is held at the constant 1.2V by feedback, and how the FEEDBACK pin passes little current. To generate the required reverse current, typically a resistor is connected from a supply voltage higher than the reference voltage. Varying that voltage, and so varying |,, has small ef- fect with the equivalent series resistance of less than an ohm at the higher currents.

Che Bs009226-31 FIGURE 3. 1.2V Reference Capacitors in parallel with the reference are allowed. See the Reference AC Stability Range typical curve for capacitance values from 20 LA to 3 mA any capacitor value is stable. With the references wide stability range with resistive and capacitive loads, a wide range of RC filter values will perform noise filtering. Adjustable Reference The FEEDBACK pin allows the reference output voltage, Vio, to vary from 1.24V to 6.3V. The reference attempts to hold V, at 1.24V. If V, is above 1.24V, the reference will con- duct current from Cathode to Anode; FEEDBACK current al- ways remains low. If FEEDBACK is connected to Anode, then V,. = V, = 1.24V. For higher voltages FEEDBACK is held at a constant voltage above Anode say 3.76V for V,, = 5V. Connecting a resistor across the constant V, generates a current I=R1/V, flowing from Cathode into FEEDBACK node. A Thevenin equivalent 3.76V is generated from FEED- BACK to Anode with R2=3.76/l. Keep | greater than one thousand times larger than FEEDBACK bias current for <0.1% error 1232 A for the military grade over the military temperature range (l25.5 YA for a 1% untrimmed error for a commercial part).

OPERATIONAL AMPLIFIERS AND COMPARATORS Any amp, comparator, or the reference may be biased in any way with no effect on the other sections of the LM613, ex- cept when a substrate diode conducts, see Electrical Char- acteristics (Note 1). For example, one amp input may be out- side the common-mode range, another amp may be operating as a comparator, and all other sections may have all terminals floating with no effect on the others. Tying in- verting input to output and non-inverting input to V~ on un- used amps is preferred. Unused comparators should have non-inverting input and output tied to V*, and inverting input tied to V-. Choosing operating points that cause oscillation, such as driving too large a capacitive load, is best avoided. Op Amp Output Stage These op amps, like the LM124 series, have flexible and relatively wide-swing output stages. There are simple rules to optimize output swing, reduce cross-over distortion, and optimize capacitive drive capability: 1. Output Swing: Unloaded, the 42 YA pull-down will bring the output within 300 mV of V over the military tempera- ture range. If more than 42 Ais required, a resistor from output to V~ will help. Swing across any load may be im- proved slightly if the load can be tied to V*, at the cost of poorer sinking open-loop voltage gain. 17 www.national.comApplication Information (continued) 2. Cross-Over Distortion: The LM613 has lower cross-over distortion (a 1 Vge deadband versus 3 Vpe for the LM124), and increased slew rate as shown in the char- acteristic curves. A resistor pull-up or pull-down will force class-A operation with only the PNP or NPN output tran- sistor conducting, eliminating cross-over distortion. 3. Capacitive Drive: Limited by the output pole caused by the output resistance driving capacitive loads, a pull-down resistor conducting 1 mA or more reduces the output stage NPN r, until the output resistance is that of the current limit 25Q. 200 pF may then be driven without oscillation. Comparator Output Stage The comparators, like the LM139 series, have open-collector output stages. A pull-up resistor must be added from each output pin to a positive voltage for the output transistor to switch properly. When the output transistor is OFF, the out- put voltage will be this external positive voltage. Typical Applications For the output voltage to be under the TTL-low voltage threshold when the output transistor is ON, the output cur- rent must be less than 8 mA (over temperature). This im- pacts the minimum value of pull-up resistor. The offset voltage may increase when the output voltage is low and the output current is less than 30 YA. Thus, for best accuracy, the pull-up resistor value should be low enough to allow the output transistor to sink more than 30 YA. Op Amp and Comparator Input Stage The lateral PNP input transistors, unlike those of most op amps, have BVego equal to the absolute maximum supply voltage. Also, they have no diode clamps to the positive sup- ply nor across the inputs. These features make the inputs look like high impedances to input sources producing large differential and common-mode voltages. +V0 3k 2N2222 2N2907 oQror DS008226-40 FIGURE 12.
