The SGM8709 is an ultra-low power comparator, which consumes only 318nA (TYP) supply current at 1.4V. The device can operate from 1.4V to 5.5V single supply, and is guaranteed to operate at 1.4V, 2.5V and 5V. It supports rail-to-rail input operation. The above features make the SGM8709 a good choice for battery-powered applications.
The SGM8709 has an open-drain output structure. When driving any resistive or capacitive load, it is capable of consuming the absolute minimum power.
The SGM8709 has a great trade-off between low power and high speed, and the propagation delay is only 6μs with 100mV overdrive at 1.4V.
In addition, the SGM8709 fits in small packages, so it is also suitable for mobile phone and handheld electronic devices.
The SGM8709 is available in Green SOT-23-5 and SC70-5 packages. It is rated over the -40℃ to +85℃ temperature range.
