Texas Instruments LM2903QDG4

LM2903QDG4 Overview
From a technical standpoint, the brand of this part is Texas Instruments, a well-known and respected company in the semiconductor industry. This particular chip falls under the Linear - Comparators category, which is a type of integrated circuit that compares the input voltage with a reference voltage and outputs a digital signal based on the comparison. The Mounting Type for this chip is Surface Mount, which means it can be directly mounted onto a printed circuit board (PCB) without the need for additional hardware. This makes it a convenient and efficient choice for manufacturers. In terms of its operating conditions, this chip can withstand a wide range of temperatures, from -40°C to 125°C, making it suitable for use in various environments. Its Part Status is Active, which means it is currently being produced and readily available for purchase. The Moisture Sensitivity Level (MSL) for this chip is 1, the highest level, indicating that it has unlimited floor life and can withstand multiple reflow cycles during the manufacturing process. This makes it a reliable and durable choice for electronic devices. From a regulatory standpoint, this chip falls under the EAR99 classification, which means it does not require a license for export and is not subject to specific export controls. This makes it a versatile and accessible option for manufacturers around the world. Its Packing Method is TR, which stands for Tape and Reel, a popular packaging method for surface mount components that allows for efficient and automated assembly. The Base Part Number for this chip is LM2903, which is a unique identifier used to distinguish it from other chips in the same series. Its Operating Supply Voltage is 9V, which is the voltage required for proper operation. The Quiescent Current for this chip is 2.5mA, which is the amount of current consumed when there is no input signal. Lastly, the Current - Input Bias (Max) is 0.25μA at 5V, indicating the maximum amount of current that can flow into the chip's input pins without causing any significant change in its output. These parameters provide important technical information for engineers and designers to consider when selecting and using this chip in their electronic designs.
