LMV7235 Description

    The LMV7235/39 are ultra low power, low voltage, 45ns comparators. They are guaranteed to operate over the full supply voltage range of 2.7V to 5V. These devices achieve a 45ns propagation delay while consuming only 65µA of supply current at 5V.

    The LMV7235/39 have a greater than rail-to-rail common mode voltage range. The input common mode voltage range extends 200mV below ground and 200mV above supply, allowing both ground and supply sensing.

    The LMV7235 features an open drain output. By connecting an external resistor, the output of the comparator can be used as a level shifter.

    The LMV7239 features a push-pull output stage. This feature allows operation without the need of an external pull-up resistor.

    The LMV7235/39 are available in the SC70-5 and SOT23-5 packages, which are ideal for systems where small size and low power is critical.
