It is designed for operation in a wide range of environments, from low-power, low-voltage applications to higher power, higher voltage applications. The series is extremely versatile in its application, offering good performance in any situation.

General Description

The NJM12903M series is a range of linear comparators which provide flexible interfacing solutions between digital and analogue systems. The series enables the user to set hysteresis while maintaining excellent linearity of the output over a wide dynamic range. This series is suitable for use in many different applications ranging from low-power low-voltage applications to higher power higher voltage applications.

Features & Benefits

The NJM12903M series offers many benefits over traditional digital and analogue interfacing solutions. It has a wide power operating range from 1V to 20V DC, and it has an extremely low input bias current. This low bias current allows the device to be used in high noise environments as it minimizes false trigger signals caused by noise. Additionally, this series features hysteresis which can be configured to the user\'s preference. The device also has an excellent linearity of the output over a wide dynamic range, providing an accurate and precise output. The series also features a wide operating temperature range and can operate in environments with high thermal energy. The series is also very versatile in its application and can be used in many different applications such as low-power, low-voltage applications, high-voltage applications such as motor controllers, and in many other analogue/digital interface solutions.

Applications

The NJM12903M series is suitable for use in many different applications, including:

• Low-power, low-voltage applications
• Motor control applications
• Analogue/Digital interfacing solutions
• High-voltage applications such as inverters and converters
• Alarm systems
• Power supplies
• Signal conditioning
• Audio systems
• Robotics
• Automotive systems

Working Principle

The NJM12903M series works by comparing the voltage of its two inputs, VIN and VOUT. When VIN is greater than VOUT, the output of the comparator will switch to a high logic level. Conversely, when VOUT is greater than VIN, the output of the comparator will switch to a low logic level. The hysteresis of the device can be configured to the user\'s preference, allowing for excellent linearity of the output over a wide dynamic range.To sum up, the NJM12903M series is an excellent linear comparator which offers excellent linearity of the output over a wide dynamic range, and is suitable for use in many different applications. Its low input bias current minimises false trigger signals caused by noise, and its wide operating temperature range and wide power range make it especially well suited for use in demanding applications.
