STMicroelectronics introduces the TS3011, a high-speed voltage comparator claiming the fastest response time at the lowest current consumption targeted at response time critical applications such as data communications equipment.

ST's TS3011

The TS3011 single comparator achieves a propagation delay of 8ns while consuming only 470MµA of supply current at 5V.

When a noise occurs in the signal, for example, minimised delay helps ensure instant data recovery and thus maintain failure-free communication traffic flow. Fast-response comparators can also find use in pulse-width modulation for audio amplifiers or as output buffers in oscilloscopes and analogue-to-digital converters.

The TS3011 single comparator achieves a propagation delay of 8ns while consuming only 470MµA of supply current at 5V, which is 50 per cent lower than other solutions in the market, according to ST.

The TS3011 integrates push-pull outputs, removing the need for a pull-up resistor, and rail-to-rail inputs with operating voltage range from 2.2V to 5V. The device delivers a stable response time over a wide temperature range of -40°C to +125°C. It is a robust solution offering superior ESD (Electrostatic Discharge Protection) capabilities and a latch-up immunity of 200mA.

Available in space-saving SMD packages, ST's TS3011 high-speed voltage comparator targets signal-conditioning applications in telecom and industrial fields. The device is in volume production, with unit pricing Rs.47.09 ($1.05) in quantities of 1,000 pieces. Further pricing options are available for larger quantities.
