The TSX3702 from STMicroelectronics is a micropower CMOS dual-voltage comparator which draws a very low current of 5μA per comparator.

The TSX3702 is an improved version of the TS3702: it draws a lower current, has a better input offset voltage, and offers enhanced ESD tolerance.

The TSX3702 is fully specified over a wide operating-temperature range of -40°C to 125°C, and is available in an automotive grade in the SO8 package version.

A wide single supply-voltage range of 2.7V to 16V gives considerable flexibility to the power- system designer. A dual supply operates in the range from ±1.35V to ±8.0V.

The TSX3702 is fully compatible with the TS3702 CMOS comparator, and is available in similar package styles, as well as additional small packages: a MiniSO8 and a 2mm x 2mm DFN8.
