GENERAL DEscriptION
The SGM8708 is a dual, rail-to-rail input and output comparator with typical 2.2μA low power supply current. The comparator operates from a wide range of 1.8V to 5.5V supply voltage, and is guaranteed to operate at 1.8V and 5V. This feature is suitable for battery-powered applications.
The product features an uncommitted internal voltage reference, comparator input common-mode around 200mV outside the power supply rails and can be operated from 1.8V to 5.5V. The internal 1.2V series reference voltage offers low 42μV/℃ drift, is stable at 10nF capacitive load, and can produce output current up to 2mA (TYP).
The SGM8708 is optimized for micro-power, single-supply operation. The push-pull output stage supports rail-to-rail output swing and allows the operation with absolute minimum power consumption when driving any capacitive or resistive load. The SGM8708 also has a latch enable input pin (LE) and complementary outputs.
The SGM8708 is available in Green SOT-23-8 and SOIC-8 packages. It is rated over the -40℃ to +85℃ temperature range.
