National Semiconductor has announced the DP83862, a low-cost, highly integrated dual-port 10/100/1000 physical layer transceiver.
The LMP7300's adjustable hysteresis improves the noise immunity of the comparator and prevents false readings by providing engineers with 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 300uV and low supply current of 10uA make it well-suited to precision battery-operated systems.
It has a wide supply voltage range of 2.7 to 12V for use in 3.3, 5V and +/-5V applications.
A 2.048V reference voltage with 0.25% maximum error provides a precise input monitoring voltage reference level.
The comparator's propagation delay is less than 5us to enable fast, precise, low-power signal detection.
