ST says low power comparator is fast

The TS3011 single comparator features a high-speed response time with rail-to-rail inputs. Specified for a supply voltage of 2.2 to 5 V, this comparator can operate over a wide temperature range of -40°C to +125°C.

The TS3011 offers micropower consumption as low as a few hundred microamperes, thus providing an excellent ratio of power consumption current versus response time.

The TS3011 includes push-pull outputs and is available in small packages (SMD): SOT23-5 and SC70-5.

Key Features

  • Propagation delay: 8 ns
  • Low current consumption: 470 μA typ at 5 V
  • Rail-to-rail inputs
  • Push-pull outputs
  • Supply operation from 2.2 to 5 V
  • Wide temperature range: -40°C to +125°C
  • ESD tolerance: 2 kV HBM/200 V MM
  • Latch-up immunity: 200 mA
  • SMD packages

ST says low power comparator is fast

STMicroelectronics has a high-speed voltage comparator with current consumption of less than 500µA.

This is significant, says ST, because of the chip’s 8ns propagation delay at a current consumption of only 470µA at 5V.

As well as signal-conditioning applications in telecoms, fast-response comparators can find use in pulse-width modulation for audio amplifiers or as output buffers in oscilloscopes and analog-to-digital converters.

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 with superior ESD (Electrostatic Discharge Protection) capabilities and a latch-up immunity of 200mA.
