Leading global semiconductors specialist ST Microelectronics has leveraged its advanced capabilities to create a new generation of comparators designed to enable improved energy efficiency and faster operation of equipment such as gas sensors, medical devices, safety systems and industrial controls.
The TS881 is the first in ST’s new generation of comparators compatible with supply voltages as low as 1.1V over a wide temperature range, enabling longer operating times with smaller batteries. Suitable for use in front-end detection and measurement circuitry, the TS881 is also faster than competing devices, allowing a significant reduction in equipment response times.
The ultra low power devices leverage ST’s innovations in analogue design with very low operating current of 210nA (typical at 25°C), drawing less than half the current of competing devices. The push-pull output circuitry reduces power consumption to the absolute minimum when driving any capacitive or resistive load.
ST will introduce dual and quad variants of the TS881, containing two and four comparators respectively in a single package. This new generation of devices extends ST’s industry-leading portfolio of comparators, which includes the TS3011 that delivers a market-leading response time of 8ns with very low current consumption.
Key features of TS881 comparators:
- Typical operating current: 210nA (@ 25°C)
- Typical propagation delay: 2µs
- Temperature range: - 40°C to +125°C
- Operating voltage range: 1.1V to 5V (1.1V operation guaranteed over full temperature range)
- ESD tolerance: 8kV HBM (Human Body Model)
- Rail-to-rail input
- Push-pull output
