STMicroelectronics has upgraded its 16V CMOS dual and quad analog comparators using the latest-generation process technology to achieve lower typical current consumption of 5µA per comparator, as well as faster propagation time and increased ESD capability of up to 4kV.
Compatible with the previous-generation ICs, the TSX393, TSX339, TSX3702, and TSX3704 further extend the performance and efficiency advantages of ST’s CMOS devices over competing bipolar comparators. With their wide single-supply voltage range of 2.7-16V, the new comparators can operate from the standard voltages used in a wide variety of applications, including industrial or automotive equipment.
The new devices are specified over the in temperature range -40°C to 125°C, and have higher ESD capability than their predecessors thereby enhancing the reliability 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 where ORing or level shifting are required. The dual TSX3702 and quad TSX3704 have push-pull outputs for reliable signaling without pull-ups. Output-drive capability of up to 20mA allows direct connection to a wide variety of analog or digital loads.
With the latest devices, ST is also introducing new, smaller package styles that ease design-in and simplify board layout and routing. The TSX393 and TSX3702 are available in a 2mm 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 3mm x 3mm 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.
ST’s new TSX-series comparators are in production now, priced from $0.395 for the TSX393 or TSX3702 (dual), $0.527 for the TSX3704 (quad), and $0.546 for the TSX339 (quad). All prices are for orders of 1000 pieces.
