National Semiconductor Introduces Highest-Accuracy Integrated Micropower Comparator Reference
SANTA CLARA, Calif. - October 31, 2007 - National Semiconductor Corporation (NYSE:NSM) today introduced a new low-power precision comparator with integrated 2.048V reference that provides adjustable hysteresis for the highest-accuracy signal detection in power supply and battery monitors, sensor interface and threshold detectors. The LMP7300 is the latest addition to the company's PowerWise® energy-efficient product family.
The LMP7300's adjustable hysteresis improves the noise immunity of the comparator and prevents false readings by providing engineers the flexibility to develop precise bidirectional threshold trip points that are positive, negative, symmetric or asymmetric. In addition, the two threshold trip points are independent of one another to further simplify designs without interdependency constraints.
The comparator's low-offset voltage of 300 µV and low supply current of 10 µA make it well-suited for precision battery-operated systems. It has a wide 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.
Built on National's proprietary VIP50 BiCMOS process technology, the LMP7300 is the latest addition to the company's precision and low-voltage, low-power amplifier families. These amplifiers dramatically improve system accuracy and power consumption.
