General Description
The GS331 consists of a single precision voltage -parator with a typical input offset voltage of 1.0m V and high voltage gain. It is specifically designed to operate from a single power supply over wide range of voltages. Operation from split power supply is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. The GS331 is available in standard SOT-23-5 package.

Note 1: Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "Remended Operating Conditions" is not implied. Exposure to "Absolute Max-imum Ratings" for extended periods may affect device reliability.
Note 2: This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector-base...
