Texas Instruments LM139AQML-SP Low Power Low Offset Voltage Quad Comparator 5962R9673801VDA

The LM139AQML-SP is a low power, low offset voltage quad comparator designed by Texas Instruments. It features four independent precision voltage comparators with a maximum offset voltage of ¬±1 mV and a low input bias current of 25 nA. The device operates over a wide supply voltage range of 2 to 36 V DC or ¬±1 to ¬±18 V DC, making it suitable for various applications, including battery-operated devices. This comparator is characterized by a very low supply current drain of 0.8 mA, independent of the supply voltage, and it can function with a single power supply, allowing for sensing near ground. The input common-mode voltage range includes ground, which enhances its versatility in different circuit configurations. The LM139AQML-SP is also radiation-hardened, with a total ionizing dose of 100 krad (Si), making it suitable for use in space and other high-radiation environments. The device is packaged in a 14-pin CFP (NAD) configuration and is rated for operation in a temperature range of -55¬8C to 125¬8C. Its low output saturation voltage of 250 mV at 4 mA and compatibility with TTL, DTL, ECL, and CMOS logic systems further enhance its applicability in various electronic designs.
