STMicroelectronics TSX series analog comparators

Click2Contact

STMicroelectronics has upgraded its 16 V CMOS dual and quad analog comparators using the latest process technology to achieve low typical current consumption of 5 µA per comparator, as well as fast propagation time and increased ESD capability of up to 4 kV.

Compatible with the previous-generation ICs, the TSX393, TSX339, TSX3702 and TSX3704 extend the performance and efficiency advantages of ST’s CMOS devices over competing bipolar comparators. With their wide single-supply voltage range of 2.7 to 16 V, the comparators can operate from the standard voltages used in a wide variety of applications, including industrial or automotive equipment.

The devices feature a temperature range of -40 to 125°C and have higher ESD capability than their predecessors, thereby enhancing the performance of sensing and control systems in harsh environments.

The TSX393 and TSX339 integrate two and four comparators respectively, and feature open-drain outputs that can help simplify circuit design. The dual TSX3702 and quad TSX3704 have push-pull outputs for signalling without pull-ups. Output-drive capability of up to 20 mA allows direct connection to a wide variety of analog or digital loads.

The TSX393 and TSX3702 are available in a 2 x 2 mm DFN8 in addition to the established SO-8, Mini-SO8 and TSSOP-8 packages. The TSX339 and TSX3704 can be ordered as a 3 x 3 mm QFN16, as well as SO-14 and TSSOP-14. ST is in the process of qualifying the SO-8 and TSSOP-14 devices according to AEC-Q100.
