Voltage comparator IC with propagation delay of 200ns and consume 30uA

STMicroelectronics says its new general-purpose voltage comparator consumes one third the current for the same response time, compared with currently available devices such as the LMV331.

TS33 offers a propagation delay of 200ns while 30 micro Amperes of supply current. The TS33 comparator IC delivers a stable response time over a wide temperature range, from -40°C to +125°C, and offers better ESD (Electrostatic Discharge Protection) capabilities. It integrates an open-drain output and rail-to-rail inputs with the wide operating voltage range, from 1.6V to 5V.

The applications suggested includes signal-conditioning applications in mobile communications, battery-operated portable electronics, and alarm and security systems.

The TS33 general-purpose voltage comparator is sampling now and ready to start volume production. Unit pricing in quantities of 1,000 pieces starts at $0.28 (TS331 - single), $0.35 (TS332 - dual) and $0.39 (TS334 - quad).
