The TS391H is a low power voltage comparator designed specifically to operate from a single supply over a wide range of voltages. Operation from split power supplies is also possible. This comparator also has a unique characteristic in that the input common-mode voltage range includes ground even though operated from a single power supply voltage.
The TS391H is a wafer form voltage comparator specifically designed to operate from a single supply over a wide range of voltages. It features very low supply current independent of the supply voltage and includes ground in its input common-mode voltage range even when operated from a single power supply.
Key electrical characteristics include an input offset voltage of 1 mV typical, a large signal voltage gain up to 200 V/mV, and response times as fast as 300 ns. The device is qualified for high-temperature applications with an operating free-air temperature range from -40°C to +150°C.
