OPA2388-Q1

The OPA2388-Q1 is a high-precision, low-power operational amplifier designed for automotive and industrial applications. It features a wide supply voltage range of 2.7 V to 5.5 V, enabling flexible integration into systems with varying power requirements. The device offers a low quiescent current of just 400 µA per channel, making it ideal for battery-powered or energy-sensitive designs. Its high gain-bandwidth product of 10 MHz ensures excellent performance in signal conditioning tasks across a broad frequency spectrum. This amplifier is optimized for precision, with a low input offset voltage of 50 µV (max) and a drift of only 0.2 µV/°C, which maintains accuracy over temperature variations—a critical factor in harsh automotive environments. The OPA2388-Q1 also provides a high open-loop gain of 120 dB, contributing to stable and accurate amplification even in demanding feedback configurations. With a rail-to-rail output swing, it can drive loads close to both supply rails, maximizing dynamic range in analog circuits. The device is qualified to AEC-Q100 Grade 1 standards, ensuring robustness under extreme automotive conditions such as high temperature, vibration, and humidity. This qualification makes it suitable for use in engine control units (ECUs), advanced driver-assistance systems (ADAS), and other safety-critical applications where reliability is paramount. Additionally, the OPA2388-Q1 includes internal EMI filtering and protection against latch-up, enhancing system stability and reducing external component count. In terms of functionality, the OPA2388-Q1 supports multiple configurations including non-inverting, inverting, and differential amplifiers, allowing designers to implement various signal conditioning solutions. It is available in small packages such as SOIC and VSSOP, facilitating compact PCB layouts. The device’s low noise performance—just 12 nV/√Hz at 1 kHz—makes it well-suited for sensing and measurement applications, such as pressure sensors, strain gauges, and temperature transducers. Its wide bandwidth and low distortion characteristics further support its use in audio and data acquisition systems requiring clean signal integrity. Engineers benefit from the OPA2388-Q1’s ease of use: it requires no external compensation, simplifying design and reducing development time. With integrated thermal shutdown and short-circuit protection, the amplifier enhances system resilience without compromising performance. These features collectively make the OPA2388-Q1 a reliable, efficient, and versatile solution for precision analog signal processing in modern electronic systems.
