OPA2197-Q1

The OPA2197-Q1 is a high-precision operational amplifier manufactured by Texas Instruments, specifically designed for automotive and industrial applications requiring exceptional accuracy and reliability. It features a low input offset voltage of 50 µV (max) and a very low offset drift of 0.2 µV/°C, ensuring stable performance across wide temperature ranges—from –40°C to +125°C—making it ideal for harsh environments. This device offers a high gain-bandwidth product of 10 MHz, enabling fast response times and excellent signal fidelity in analog signal conditioning circuits. With a low noise density of 8 nV/√Hz at 1 kHz, the OPA2197-Q1 maintains clean output signals even in sensitive measurement systems such as sensor interfaces and precision instrumentation. Its low distortion (THD = 0.001%) ensures minimal signal degradation, which is critical in audio and data acquisition applications. The OPA2197-Q1 operates from a single supply ranging from 2.7 V to 5.5 V, making it compatible with both low-voltage and standard power rails. It includes integrated protection features such as ESD robustness (±2 kV HBM), short-circuit current limiting, and thermal shutdown, enhancing system-level reliability and reducing design complexity. The device also supports rail-to-rail input and output operation, maximizing dynamic range and efficiency in battery-powered or space-constrained designs. Designed to meet AEC-Q100 Grade 1 qualification standards, this op amp is suitable for demanding automotive applications including engine control units (ECUs), ADAS systems, battery management systems (BMS), and infotainment modules. Its low power consumption of 2.4 mA per channel allows efficient use in energy-sensitive systems without compromising performance. In addition to its robust electrical specifications, the OPA2197-Q1 provides ease of integration through its small SOIC-8 package and compatibility with standard PCB assembly processes. It supports flexible configurations for inverting, non-inverting, differential, and integrator circuits, offering engineers versatile options for analog front-end design. The device’s stability over frequency and load conditions makes it particularly effective in filtering, amplification, and buffering tasks where precision and consistency are paramount.
