Rohm Semiconductor LM2903MX

LM2903MX Overview
Rohm Semiconductor is a well-known brand in the electronics industry, known for its high-quality and reliable products. One of their offerings is the Linear - Comparators chip, which falls under the Linear - Comparators category. This chip is designed to accurately compare two analog signals and provide a digital output based on the comparison result. It is a crucial component in many electronic devices, such as amplifiers, oscillators, and filters. The mount for this chip is Surface Mount, which is a popular method of mounting electronic components on a printed circuit board (PCB). This allows for a more compact and efficient design, as well as easier assembly and maintenance. The package/case for this chip is 8-SOIC (0.154, 3.90mm Width), which refers to the size and shape of the chip. This size is commonly used in the industry, making it compatible with a wide range of PCB designs. The terminal form for this chip is GULL WING, which refers to the shape of the metal leads that are used to connect the chip to the PCB. This form is known for its stability and reliability, ensuring a secure connection between the chip and the PCB. The chip has 2 functions, making it versatile and suitable for various applications. The supply voltage for this chip is 5V, which is a standard voltage for many electronic devices. This ensures compatibility with other components in the circuit and makes it easy to integrate into existing designs. The base part number for this chip is LM2903, which is a unique identifier used to differentiate it from other chips in the same series. In terms of performance, this chip has a quiescent current of 2.5mA, which is the current consumed by the chip when no input signal is present. This low quiescent current makes it energy-efficient and suitable for battery-powered devices. The response time for this chip is 700 ns, which is the time it takes for the chip to provide an output after receiving an input signal. This fast response time is crucial for accurate and real-time signal processing. Furthermore, this chip has an input offset voltage (Vos) of 7mV, which is the difference between the two input voltages required to produce a zero output. A lower input offset voltage ensures more accurate comparisons and a more precise output. Lastly, this chip is not radiation hardened, which means it is not designed to withstand high levels of radiation. This parameter is important for applications in harsh environments, such as aerospace or military equipment. In conclusion, the Rohm Semiconductor Linear - Comparators chip offers high-quality and reliable performance with its surface mount, GULL WING terminal form, and 5V supply voltage. Its 2 functions, low quiescent current, fast response time, and low input offset voltage make it suitable for a wide range of applications. However, it should be noted that it is not radiation hardened and may not be suitable for use in extreme environments.
