LM139/LM239/LM339/LM2901/LM3302

Low Power Low Offset Voltage Quad Comparators

General Description

The LM139 series consists of four independent precision voltage comparators with an offset voltage specification as low as 2 mV max for all four comparators. These 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 magnitude 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 LM139 series was designed to directly interface with TTL and CMOS. When operated from both plus and minus power supplies, they will directly interface with MOS logic Ð where the low power drain of the LM339 is a distinct advantage over standard comparators.

Note 4: For operating at high temperatures, the LM339/LM339A, LM2901, LM3302 must be derated based on a 125ÊC maximum junction temperature and a thermal resistance of 95ÊC/W which applies for the device soldered in a printed circuit board, operating in a still air ambient. The LM239 and LM139 must be derated based on a 150ÊC maximum junction temperature. The low bias dissipation and the ªON-OFFº characteristic of the outputs keeps the chip dissipation very smal(PD≤100 mW), provided the output transistors are allowed to saturate.

Note 5: 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 20 mA independent of the magnitude of V+.

Note 6: 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 −0.3 V DC (at 25Ê)C.

Note 7: These specifications are limited to −55ÊC ≤TA≤+125ÊC, for the LM139/LM139A. With the LM239/LM239A, all temperature specifications are limited to −25ÊC ≤TA≤+85ÊC, the LM339/LM339A temperature specifications are limited to 0ÊC ≤TA≤+70ÊC, and the LM2901, LM3302 temperature range is −40ÊC ≤TA≤+85ÊC.

Note 8: The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of the output so no loading change exists on the reference or input lines.

Note 9: The input common-mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of the common-mode voltage range is V+ −1.5V at 25ÊC, but either or both inputs can go to +30 V DC without damage (25V for LM3302), independent of the magnitude of V+.

Note 10: The response time specified is a 100 mV input step with 5 mV overdrive. For larger overdrive signals 300 ns can be obtained, see typical performance characteristics section.

Note 11: 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 −0.3 V DC (or 0.3 VDCbelow the magnitude of the negative power supply, if used) (at 25ÊC).

Note 12: At output switch point, VO 1.4 VDC, RS=0Ω with V+ from 5 VDC to 30 VDC; and over the full input common-mode range (0 VDC to V+ −1.5 V DC), at 25ÊC. For LM3302, V+ from 5 VDC to 28 VDC.

Note 13: Refer to RETS139AX for LM139A military specifications and to RETS139X for LM139 military specifications.
