ON Semiconductor LM2903V Dual Voltage Comparator

The LM2903V from ON Semiconductor is a versatile dual differential voltage comparator that is designed to operate over a wide range of voltages, from a single 2V supply up to a dual ±18V supply. This component is highly appreciated for its reliability and efficiency in a variety of electronic applications.

Featuring low input bias and offset currents, the LM2903V provides precise voltage comparison. Its open collector output offers the flexibility to interface with different logic levels, making it suitable for real-world applications such as limit comparators, simple analog to digital converters, pulse, square wave and time delay generators.

The device is characterized for operation from -40°C to +125°C, ensuring performance in even the most demanding environments. Its robust design includes the capability to drive loads directly or through pull-up resistors, offering designers a high degree of versatility. The LM2903V's low supply current drain is independent of the magnitude of the power supply voltage, which contributes to its energy-efficient operation.

Key features of the LM2903V include:

• Wide power supply range: Single supply 2V to 36V, or dual supplies ±1V to ±18V
• Low supply current drain independent of supply voltage: 0.8mA typical
• Low input biasing current: 25nA typical
• Low input offset current: ±5nA typical
• Input common-mode voltage range includes ground
• Differential input voltage range equal to the power supply voltage
• Low output saturation voltage: 250mV typical at 4mA

The LM2903V is available in multiple package options, including the space-saving surface-mount packages, providing flexibility for various PCB layouts and design constraints. With its proven performance and ON Semiconductor's commitment to quality, the LM2903V is an excellent choice for designers looking for a reliable and cost-effective voltage comparator solution.
