LM613 Dual Operational Amplifiers, Dual Comparators, and Adjustable Reference

August 2000

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 pro­viding higher speed and bandwidth along with low supply
current. This device was specifically designed to lower cost
and board space requirements in transducer, test, measure­ment, and data acquisition systems.

Combining a stable voltage reference with wide output swing
op-amps makes the LM613 ideal for single supply transduc­ers, 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 dy­namic output impedance (1Ω typical), excellent initial toler­ance (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 com­monly encountered in CMOS data acquisition systems.

As a member of National’s Super-Block
is a space-saving monolithic alternative to a multi-chip solu­tion, offering a high level of integration without sacrificing
performance.

Note 1: Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply when operating the de­vice beyond its rated operating conditions.

Note 2: Input voltage above V
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 T

soldered to copper-clad board with dissipation from one comparator or reference output transistor, nominal θ
WM package.

Note 6: Human body model, 100 pF discharged through a 1.5 kΩ resistor.
Note 7: Typical values in standard typeface are for T

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
and 10V.

Note 10: V
Note 11: Average reference drift is calculated from the measurement of the reference voltage at 25˚C and at the temperature extremes. The drift, in ppm/˚C, is

Note 12: Hysteresis is the change in V
hysteresis to the typical value, its junction temperature should be cycled in the following pattern, spiraling in toward 25˚C: 25˚C, 85˚C, −40˚C, 70˚C, 0˚C, 25˚C.

Note 13: Low contact resistance is required for accurate measurement.
