LM2903DR General Description
The LM2903DR is a dual differential comparator integrated circuit (IC) manufactured by Texas Instruments. It is designed for use in a wide range of applications, including voltage detection, level shifting, and signal conditioning. The LM2903DR features two independent comparators with open-collector outputs, allowing for flexibility in the design of various circuits. The IC has a wide supply voltage range of 2V to 36V and can operate in temperatures ranging from -40°C to 105°C, making it suitable for use in harsh environments. Key specifications of the LM2903DR include a response time of 1.3 μs, a low input bias current of 25 nA, and a low input offset current of 5 nA. The IC also has internal hysteresis to prevent oscillations around the threshold voltage.
