LMV7239
- VS = 5 V, TA = 25°C (Typical Values Unless Otherwise Specified)
- Propagation Delay: 75 ns
- Low supply Current: 65 µA
- Rail-to-Rail Input
- Open Drain and Push-Pull Output
- Ideal for 2.7-V and 5-V, Single-Supply Applications
- Available in Space-Saving Packages:
- 5-Pin SOT-23
- 5-Pin SC70
The LMV7235 and LMV7239 are ultra low power, low voltage, 75-ns comparators. They are ensured to operate over the full supply voltage range of 2.7 V to 5.5 V. These devices achieve a 75-ns propagation delay while consuming only 65 µA of supply current at 5 V.
The LMV7235 and LMV7239 have a greater than rail-to-rail common-mode voltage range. The input common mode voltage range extends 200 mV below ground and 200 mV 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 pullup resistor.
The LMV7235 and LMV7239 are available in the 5-pin SC70 and 5-pin SOT-23 packages, which are ideal for systems where small size and low power is critical.
