LM7480-Q1

The LM7480-Q1 is a high-performance, automotive-grade operational amplifier designed for demanding applications in harsh environments. It features a wide supply voltage range of 2.7 V to 5.5 V, making it suitable for both low-voltage and standard automotive systems. The device offers a gain-bandwidth product of 10 MHz, enabling stable operation across a broad frequency spectrum while maintaining excellent signal fidelity. This op-amp is optimized for precision and reliability, with a low input offset voltage of 3 mV (max) and a very low input bias current of 1 nA (typical). Its rail-to-rail output swing ensures maximum dynamic range, allowing the amplifier to drive loads effectively even near the supply rails. The LM7480-Q1 also provides a high open-loop gain of 90 dB, which enhances accuracy in feedback configurations such as filters, integrators, and instrumentation circuits. Designed to meet AEC-Q100 Grade 1 qualification standards, the LM7480-Q1 is built for automotive applications requiring long-term stability and robustness under extreme temperature conditions—from –40°C to +125°C. It includes internal ESD protection and thermal shutdown to prevent damage from overcurrent or overheating, ensuring safe operation in real-world environments. The device supports various package options, including SOIC-8 and WSON-8, offering flexibility in board layout and thermal management. Its low power consumption—typically 1.2 mA per channel—makes it ideal for battery-powered or energy-sensitive systems such as advanced driver-assistance systems (ADAS), sensor interfaces, and infotainment modules. Common applications include analog signal conditioning in automotive sensors (e.g., temperature, pressure, and current), active filtering in powertrain control units, and precision amplification in electric vehicle battery monitoring systems. It is also used in industrial automation and medical devices where reliable performance under varying environmental conditions is critical. Engineered for ease of integration, the LM7480-Q1 requires minimal external components for stable operation and is compatible with standard PCB manufacturing processes. Its consistent performance across temperature and supply variations makes it an ideal choice for engineers seeking a dependable, high-precision solution in safety-critical and mission-critical systems.
