具有漏极开路/推挽式输出的 75 nsec、超低功耗、低压、轨到轨输入比较器 - LMV7239-Q1


  • LMV7239  - 器件与被比较器件具有相似功能,但并不功能等效。 


The LMV7235, LMV7239 and LMV7239-Q1 are ultra low power, low voltage, 75-ns comparators. They are guaranteed 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, LMV7239 and LMV7239-Q1 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 and LMV7239-Q1 features a push-pull output stage. This feature allows operation without the need of an external pull-up resistor.

The LMV7235, LMV7239 and LMV7239-Q1 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.
