Ultra low-power family of comparators enhances portable technology for healthcare, safety and security

The TS881 is the first in ST’s new generation of comparators compatible with supply voltages as low as 1.1 V 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 reduction in equipment response times.

Applying ST’s innovations in analog design, with low operating current of 210 nA (typical at 25°C), the TS881 draws less than half the current of competing devices. Moreover the push-pull output circuitry reduces power consumption to the absolute minimum when driving any capacitive or resistive load.

The TS881 will be joined in 2013 by dual and quad variants containing two and four comparators in a single package. The new generation of devices extends ST’s industry-leading portfolio of comparators, which includes the TS3011, announced in 2011, delivering the market’s fastest response time of 8 ns with low current consumption.

The TS881 features a typical propagation delay of 2 µs and has a temperature range of -40°C to +125°C.  The device’s operating voltage range is 1.1 V to 5 V (1.1 V operation guaranteed over full temperature range) and exhibits an ESD tolerance of 8 kV HBM (Human Body Model).

Availability and Pricing

The TS881 is in production now and available in the 2 x 1.25 mm SC-70 package, priced from $0.39 for orders over 1,000 pieces.
