LOW POWER LOW OFFSET VOLTAGE DUAL COMPARATORS

General Description

The LM193A consists of two independent precision voltage comparators with an offset

voltage specification as low as 2.0mV max for two comparators which were designed

specifically to operate from a single power supply over a wide range of voltages.

Operation from split power supplies is also possible and the low power supply current

drain is independent of the magniture of the power supply voltage. These comparators also

have a unique characteristic in that the input common-mode voltage range includes ground,

even though operated from a single power supply voltage.

Application areas include limit comparators, simple analog to digital converters; pulse,

squarewave and time delay generators; wide range VCO; MOS clock timers; multivibrators and

high voltage digital logic gates. The LM193A was designed to directly interface with TTL

and CMOS. When operated from both plus and minus power supplies, the LM193A will directly

interface with MOS logic where their low power drain is a distinct advantage over standard

comparators.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.

Operating Ratings indicate conditions for which the device is functional, but do not

guarantee specific performance limits. For guaranteed specifications and test

conditions, see the Electrical Characteristics. The guaranteed specifications apply

only for the test conditions listed. Some performance characteristics may degrade

when the device is not operated under the listed test conditions.

Note 2: The maximum power dissipation must be derated at elevated temperatures and is

dictated by Tjmax (maximum junction temperature ), ThetaJA (package junction to

ambient thermal resistance), and TA (ambient temperature). The maximum allowable

power dissipation at any temperature is Pdmax = (Tjmax - TA)/ThetaJA or the number

given in the Absolute Maximum Ratings, whichever is lower.

Note 3: The LM193A must be derated based on a 150 C maximum junction temperature. The low

bias dissipation and the ON-OFF characteristic of the outputs keeps the chip

dissipation very small (PD<100mV), provided the output transistors are allowed to

saturate.

Note 4: Short circuits from the output to V+ can cause excessive heating and eventual

destruction. When considering short circuits to ground, the maximum output current is

approximately 20mA independent of the magnitude of V+.

(Continued)

Note 5: This input current will only exist when the voltage at any of the input leads is

driven negative. It is due to the collector-base junction of the input PNP

transistors becoming forward biased and thereby acting as input diode clamps. In

addition to this diode action, there is also lateral NPN parasitic transistor action

on the IC chip. This transistor action can cause the output voltages of the

comparators to go to the V+ voltage level (or to ground for a large overdrive) for

the time duration that an input is driven negative. This is not destructive and

normal output states will re-establish when the input voltage, which was negative,

again returns to a value greater than -0.3Vdc.

Note 6: Positive excursions of input voltage may exceed the power supply level. As long as

the other voltage remains within the common-mode range, the comparator will provide a

proper output state. The low input voltage state must not be less than -0.3Vdc (or

0.3Vdc below the magnitude of the negative power supply, if used).

Note 7: Human body model, 1.5K Ohms in series with 100pF.
