OPA180-Q1

The OPA180-Q1 is a precision operational amplifier manufactured by Texas Instruments, designed for high-performance analog signal conditioning in automotive and industrial applications. It features a low offset voltage of 25 µV (maximum) and a very low offset drift of 0.1 µV/°C, ensuring stable performance over temperature variations. The device offers a wide gain bandwidth product of 10 MHz, enabling accurate amplification of signals across a broad frequency range. This op-amp operates from a single supply voltage ranging from 2.7 V to 5.5 V, making it suitable for both low-voltage and standard power systems. Its rail-to-rail input and output capabilities allow maximum signal swing without distortion, enhancing dynamic range in sensor interface circuits. The OPA180-Q1 delivers a high slew rate of 6.5 V/µs, supporting fast transient response in real-time signal processing tasks. Engineered for robustness in harsh environments, the OPA180-Q1 meets AEC-Q100 Grade 1 qualification standards, ensuring reliability in automotive systems such as engine control units, battery management, and ADAS sensors. It includes integrated EMI filtering and has a low noise level of 1.3 µV RMS (in the 10 Hz to 10 kHz band), minimizing interference in sensitive measurement applications. The device supports multiple package options including SOIC, TSSOP, and WSON, providing flexibility in PCB design and thermal management. With a quiescent current of just 140 µA per channel, it is optimized for power-sensitive applications like portable instruments and energy-efficient systems. Its wide operating temperature range—from –40°C to +125°C—makes it ideal for use in extreme conditions found in automotive and industrial settings. In practical applications, the OPA180-Q1 excels in precision instrumentation, such as current sensing, filter circuits, and transducer signal conditioning. It can be used in bridge amplifiers, active filters, and buffer stages where accuracy and stability are critical. Its low distortion and high CMRR (common-mode rejection ratio of 90 dB at 1 kHz) ensure clean signal integrity even in noisy environments. The OPA180-Q1 is also compatible with TI’s broader ecosystem, including simulation tools and evaluation modules, allowing engineers to quickly prototype and validate designs. Its consistent performance, combined with automotive-grade reliability and low power consumption, positions it as a preferred choice for demanding analog front-end solutions.
