LM2901AV-Q1

The LM2901AV-Q1 is a dual operational amplifier manufactured by Texas Instruments, designed for high reliability in automotive and industrial applications. It features a wide supply voltage range from 3.0 V to 32 V, enabling flexible integration into various power systems. The device operates with a low quiescent current of typically 650 µA per amplifier, making it ideal for battery-powered or energy-sensitive designs. Its high gain-bandwidth product of 1.2 MHz ensures stable performance across a broad frequency spectrum. This operational amplifier offers excellent DC precision, with a typical input offset voltage of 2 mV and a maximum input bias current of 25 nA. It includes internal compensation for stability in both inverting and non-inverting configurations, eliminating the need for external components in many applications. The LM2901AV-Q1 is specified over an extended temperature range from -40°C to +125°C, meeting AEC-Q100 Grade 1 qualification standards for automotive use, which guarantees robustness under harsh environmental conditions such as vibration, thermal cycling, and humidity exposure. The device supports rail-to-rail output swing, allowing efficient utilization of the full supply voltage range without signal clipping. It also provides high common-mode rejection ratio (CMRR) and power-supply rejection ratio (PSRR), ensuring accurate signal amplification even in noisy environments. These characteristics make it suitable for analog signal conditioning tasks such as filtering, level shifting, and sensor interfacing. Common applications include automotive systems like engine control units (ECUs), battery management systems, and body electronics; industrial equipment such as process control sensors, data acquisition modules, and motor drivers; and consumer electronics requiring reliable analog signal processing. The LM2901AV-Q1’s pin compatibility with standard 8-pin DIP and SO packages simplifies design migration and reduces prototyping time. Texas Instruments ensures quality through rigorous testing and compliance with automotive safety standards, including ESD protection up to ±2 kV HBM and short-circuit current limiting. The part is available in lead-free (Pb-free) packaging, aligning with RoHS and environmental regulations. With its combination of performance, reliability, and ease of integration, the LM2901AV-Q1 serves as a versatile solution for engineers seeking robust analog amplification in demanding environments.
