ON Semiconductor LM2901VDR2G: Quadruple Differential Comparators

The LM2901VDR2G from ON Semiconductor is a versatile and robust integrated circuit, designed to function as a quadruple differential comparator. This device is commonly used in a wide array of applications, including industrial, automotive, and consumer electronics, where precision voltage comparison is crucial. It is designed to operate from a single power supply over a wide range of voltages or from dual power supplies.

Each of the four independent comparators within the LM2901VDR2G is designed to directly interface with TTL or CMOS logic levels, making it a suitable choice for digital systems. The comparators are capable of comparing voltages near the ground potential, even when operating from a single supply, and their open-collector outputs can be connected to achieve wired-AND relationships.

The LM2901VDR2G offers several features that make it a reliable and efficient choice for various comparison tasks:

• Wide Supply Range: The device can be powered by a supply voltage ranging from 2V to 36V when using a single supply, or ±1V to ±18V in dual supply mode, providing flexibility in different circuit configurations.
• Low Supply Current Drain: It is designed to have a low supply current drain, independent of the magnitude of the power supply voltage, making it energy efficient and ideal for battery-powered applications.
• Low Input Biasing Current: The comparators have a low input bias and offset currents, which enhances the accuracy of the device in precision voltage monitoring tasks.
• Offset Voltage: The input offset voltage is typically 2mV, contributing to the comparators' precise performance.
• Input Common-Mode Voltage Range: The device includes an input common-mode voltage range that includes ground, even when operated from a single power supply voltage.
• Output Compatibility: The open-collector outputs ensure compatibility with a variety of logic types and allow for wired-AND connections.

The LM2901VDR2G is available in a 14-pin SOIC package, providing a compact solution for space-constrained applications. Its robust design includes features that protect against damage from high-voltage transient events, making it a durable choice for harsh operating environments. With its combination of versatility, efficiency, and durability, the LM2901VDR2G is an excellent choice for designers looking for a reliable comparator solution.
