TILMV393IDGKR
Overview
The LMV393IDGKR is a dual-channel general-purpose voltage comparator from Texas Instruments featuring open-collector outputs. It is designed for low-voltage operation between 2.7V and 5.5V, making it suitable for battery-powered systems and portable electronics. With a quiescent current of only 50 microamps at 2.7V for both channels, it provides an energy-efficient solution for signal monitoring and level detection.
Why Choose This Part
This comparator offers a significant reduction in power consumption compared to the legacy LM393, while operating at lower supply voltages. The space-saving 8-VSSOP package helps reduce PCB footprint in dense designs like vacuum robots. Its open-collector output provides flexibility in driving various loads up to 84mA at 5V.
Applications
Key Specifications
Getting Started
To evaluate this part, use a standard 8-pin VSSOP breakout board for breadboarding or prototype testing. Ensure a pull-up resistor is connected to the output pin, as the open-collector architecture cannot drive high without one. Decouple the supply pin with a 0.1uF ceramic capacitor placed as close to the IC as possible to minimize switching noise.
