GENERAL DEscriptION
The SGM8710 is a single, 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 SGM8710 is optimized for micro-power, single-supply operation. The open-drain output stage allows for operation with absolute minimum power consumption when driving any capacitive or resistive load. The SGM8710 also has a latch enable input pin (LE).
The product features an uncommitted internal voltage reference, comparator input common-mode around 200mV outside the power supply rails and can be operated with a single power supply 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 SGM8710 is available in Green SOT-23-6 and SOT-23-8 packages. The small package makes this device ideal for use in hand-held electronics and mobile phone applications. It is rated over the -40℃ to +85℃ temperature range.
