LM2903DR

The LM2903DR is a dual comparator integrated circuit designed for a wide range of applications. It features low input offset voltage and low input offset current, making it suitable for precise voltage comparison tasks. The device operates with a single supply voltage ranging from 2.0 V to 30 V or a split supply voltage ranging from 1.0 V to 15 V, providing flexibility in power supply configurations.

The LM2903DR has two independent comparator channels, each with an open-collector output. This output type allows for easy interfacing with various digital circuits, including TTL, CMOS, and other logic families. The comparator’s response time is typically 1.5 microseconds, ensuring fast and reliable operation.

Key features of the LM2903DR include:

• Dual independent comparator channels
• Low input offset voltage (5.0 mV max)
• Low input offset current (5.0 nA)
• Wide supply voltage range (2.0 V to 30 V single supply, 1.0 V to 15 V split supply)
• Open-collector outputs
• Fast response time (1.5 microseconds typical)
• Low power consumption
• ESD protection on all pins

The LM2903DR is well-suited for a variety of applications, such as level detection, window comparators, and other circuits requiring precise voltage comparisons. Its compact packaging and low power consumption make it an ideal choice for portable and battery-powered devices.

Please note that specific electrical characteristics and operating conditions may vary depending on the manufacturer and version of the LM2903DR. Therefore, it is essential to consult the relevant datasheet for detailed information on performance, pin configurations, and recommended operating conditions.
