National Semiconductor introduced a low-power precision comparator with integrated 2.048V reference that provides adjustable hysteresis for signal detection in power supply and battery monitors, sensor interface and threshold detectors. The LMP7300 is a addition to the company’s PowerWise energy-efficient product family.

The comparator’s offset voltage of 300 µV and supply current of 10 µA make it well-suited for precision battery-operated systems. It has a supply voltage range of 2.7V to 12V for use in 3.3V, 5V, and plus and minus 5V applications. A 2.048V reference voltage with 0.25 percent maximum error provides a precise input monitoring voltage reference level. The comparator’s propagation delay is less than 5 microseconds to enable fast, precise, low-power signal detection.

The LMP7300 is available in an 8-pin SOIC package for $1.05 in 1,000-unit quantities.
