CMOS analogue comparators boost efficiency

STMicroelectronics has upgraded its 16V CMOS dual and quad analogue comparators. Using the latest process technology, the comparators are said to achieve a lower typical current consumption of 5µA per comparator, as well as faster propagation time and increased ESD capability of up to 4kV.

With a single supply voltage range of 2.7 to 16V, the comparators can operate from the standard voltages used in a range of applications, including industrial or automotive equipment.

Compatible with the previous generation ICs, the devices have higher ESD capability than their predecessors, thereby enhancing the reliability of sensing and control systems in harsh environments. The comparators are specified over temperatures ranging from -40 to 125°C.

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

The company is also introducing smaller package styles that it claims ease design-in and simplify board layout and routing. The TSX393 and TSX3702 are available in a 2 x 2mm 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 3mm QFN16, as well as SO-14 and TSSOP-14.
