LM2903DTR

The LM2903DTR is a dual low-power voltage comparator designed for operation over a wide voltage range with either a single or dual power supply. It features two independent and precise comparators with an input offset voltage of no more than 2.0mV, ensuring accurate comparison of input signals.

The LM2903DTR boasts a wide operating voltage range, supporting single power supplies from 2.0V to 36V and dual power supplies from ±1.0V to ±18V. It consumes low power, with a typical power current of 0.8mA that is independent of the power supply voltage. Additionally, the comparator has low input bias current (25nA) and low input offset current (5.0nA), contributing to its overall efficiency and performance.

The comparator’s input common-mode voltage range can reach zero level even when operated from a single power supply, making it suitable for various applications. The output section of the LM2903DTR is an open-collector, emitter-grounded NPN output transistor, which allows for easy interfacing with other circuits. The output can be connected to other open-collector outputs to achieve a wired-AND relationship.The LM2903DTR is packaged in either DIP8 or SOP8 form factors, providing flexibility in circuit design and integration. It is widely used in consumer and industrial electronics, including power supplies, oscillators, peak detectors, logic voltage converters, and more. Its high-speed operation and low power consumption make it an ideal choice for applications that require precise voltage comparisons and efficient power management.

Overall, the LM2903DTR is a versatile and reliable dual voltage comparator that offers excellent performance and easy integration into various circuit designs.
