The STMicroelectronics LM2903YDT is a dual low power voltage comparator from the LM2903 Series, offering two independent channels in an 8-pin surface mount SOIC package. It operates from a 2V to 36V supply, draws a nominal 400µA, and delivers a 250nA input bias current with a 7mV input offset voltage. The comparator provides a TTL output type with 16mA output current and a 1.3µs response time. LM2903YDT is rated for -40°C to 125°C operation, lead free, RoHS compliant, MSL 1, and supplied on tape and reel.

Voltage comparators are used to convert an analog input into a clean digital decision, covering threshold detection, zero-crossing sensing, window comparison, level shifting, and simple oscillator or timing circuits. The wide 2V to 36V supply range makes this part usable across 5V logic boards, 12V automotive rails, and 24V industrial supplies without additional regulation. Hardware engineers in industrial control, automotive electronics, power supply monitoring, and general embedded design specify dual comparators of this class as a low-cost building block.
