The LM139AFKB from Texas Instruments is a quad differential comparator IC. It is designed to operate from a single power supply with a wide voltage range from 2 V to 36 V, or from dual supplies ranging from ±1 V to ±18 V. The device exhibits low supply-current drain, which is independent of the supply voltage, typically drawing only 0.8 mA. It also features low input bias current of 25 nA and a low input offset voltage of 2 mV.
The common-mode input voltage range includes ground, and the differential input voltage range is equal to the maximum-rated supply voltage of ±36 V. The output saturation voltage is low, and the output is compatible with TTL, MOS, and CMOS logic levels. This comparator is housed in a 20-pin LCCC package and operates within a temperature range of -55°C to 125°C.
This part is compliant to MIL-PRF-38535, with all parameters tested unless otherwise noted. For other products, production processing does not necessarily include testing of all parameters. The LM139AFKB is suitable for applications requiring precise voltage comparison across a broad spectrum of operating conditions.
