OPA2836-Q1

The OPA2836-Q1 is a high-performance, low-noise operational amplifier manufactured by Texas Instruments, specifically designed for automotive and industrial applications requiring robust reliability and precision. It operates from a single supply voltage ranging from 2.7 V to 5.5 V, making it suitable for systems with varying power constraints. The device features a wide bandwidth of 9 MHz, enabling fast signal processing in dynamic environments, while maintaining excellent gain accuracy and stability across temperature ranges. This op-amp offers a low input offset voltage of 200 µV (max) and a very low noise density of just 1.6 nV/√Hz at 1 kHz, ensuring high-fidelity signal amplification in sensitive measurement circuits. Its rail-to-rail output stage allows for maximum signal swing, improving dynamic range without sacrificing linearity. The OPA2836-Q1 also provides a high slew rate of 14 V/µs, which supports rapid transient response—ideal for filtering, sensor signal conditioning, and active filter designs. Designed for automotive qualification (AEC-Q100 Grade 1), the OPA2836-Q1 meets stringent reliability standards, including thermal cycling, humidity testing, and ESD immunity. This makes it well-suited for use in engine control units (ECUs), advanced driver-assistance systems (ADAS), and infotainment systems where long-term performance under harsh conditions is critical. The device is available in small packages such as SOIC-8 and TSSOP-8, offering space-efficient integration into compact PCB layouts. Functionally, the OPA2836-Q1 supports both inverting and non-inverting configurations, enabling flexible circuit design for applications like current sensing, bridge amplifiers, and precision instrumentation. It includes internal frequency compensation to simplify stability in feedback networks, reducing the need for external components. Additionally, its low quiescent current of 2.3 mA per channel helps optimize power efficiency in battery-powered or energy-conscious systems. In summary, the OPA2836-Q1 delivers exceptional performance in terms of speed, noise, and precision, making it an ideal choice for demanding analog front-end applications in automotive and industrial markets.
