The LM339 from Texas Instruments is a versatile quad differential comparator IC. It is designed to operate from a wide range of single power supplies, from 2V up to 36V, or from dual supplies ranging from ±1V to ±18V. This device features a low supply-current drain that is independent of the supply voltage, typically drawing only 0.8 mA.
Key electrical characteristics include a low input bias current of 25 nA (typical) and a low input offset voltage of 2 mV (typical). The common-mode input voltage range includes ground, and the differential input voltage range can extend up to the maximum-rated supply voltage of ±36V. The output is compatible with TTL, MOS, and CMOS logic levels and features an open-collector output type.
This comparator is suitable for various industrial and automotive applications, including power supervision, oscillators, peak detectors, and logic voltage translation. It is available in surface-mount packages like SOIC, TSSOP, and SSOP, with a standard package quantity of 14 leads.
