The LM2903VQPWR is a dual operational comparator made by Texas Instruments. It is a precision voltage comparator with a wide input dynamic range and high output voltage swing. The device is designed to detect small input voltage differences for applications such as level detection, voltage comparison, amplification, hysteresis, and switching. It features low input offset voltage and low drift over temperature, low input bias current, and fast response time. The LM2903VQPWR features two independent differential inputs, allowing for single, dual, or differential voltage comparison. It is available in many package options including SOIC, PDIP, and VSSOP.
