Summary of ST says low power comparator is fast
The TS3011 is a high-speed, micropower voltage comparator by STMicroelectronics featuring rail-to-rail inputs and push-pull outputs. It operates between 2.2V and 5V with a propagation delay of 8ns and consumes only 470µA at 5V. Designed for signal conditioning, PWM audio amplifiers, and ADCs, it offers robust ESD protection and latch-up immunity across a wide temperature range from -40°C to +125°C.
Parts used in the TS3011 Project:
- TS3011 single comparator
- SOT23-5 SMD package
- SC70-5 SMD package
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.

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.
