LM2903M General Description

LM2903M is a dual voltage comparator with open-collector outputs, designed for a wide range of applications such as power management, battery management, and sensor interfaces. The device has a wide input voltage range of ±1.5V to ±18V, making it suitable for both analog and digital applications. It has a fast response time of 1.3μs, ensuring accurate comparison of input signals. The device features a low input bias current of 25nA, minimizing errors in voltage measurements. The LM2903M also has a high common-mode rejection ratio of 80dB, reducing the effects of noise and interference on the output signal. The comparator is housed in an industry-standard 8-pin SOIC package, making it easy to integrate into existing designs. It operates over a wide temperature range of -40°C to 125°C, allowing for reliable performance in harsh environments.

Key Features

LM2903M is a dual voltage comparator with a wide range of operating voltage (2V to 36V), low input offset voltage (2mV), low input bias current (25nA), open-collector outputs, and a temperature range of -40°C to 125°C

It also has high gain and response time, making it suitable for precision and high-speed applications

Application

The LM2903M is commonly used in voltage comparator applications, such as overvoltage and undervoltage detection, window comparators, and signal conditioning circuits

It is also used in battery management systems, power supplies, industrial automation, and automotive electronics due to its high precision and low power consumption
