The LMV7291 is a rail-to-rail input low power comparator, characterized at supply voltage 1.8V, 2.7V and 5.0V. It consumes only 9uA supply current per channel while achieving a 800ns propagation delay.

The LMV7291 is available in SC70 package. With this tiny package, the PC board area can be significantly reduced. It is ideal for low voltage, low power and space critical designs.

The LMV7291 features a push-pull output stage which allows operation with minimum power consumption when driving a load.

The LMV7291 is built with Texas Instruments' advance submicron silicon-gate BiCMOS process. It has bipolar inputs for improved noise performance and CMOS outputs for rail-to-rail output swing.

TIPD144 — 具有磁滯功能的比較器參考設計

此 TI 驗證設計實作了具備磁滯現象的比較器。  比較器用於區分兩種不同的訊號位準。  例如，比較器可以區分過溫與正常溫度條件。  比較閾值處的雜訊或訊號變化會導致多次轉換。  磁滯設定了上限與下限閾值，以消除由雜訊引起的多次轉換。
