OPA171AIDBVR – TEXAS INSTRUMENTS

The Texas Instruments OPA171AIDBVR is a single, precision, rail-to-rail input/output operational amplifier packaged in a small, space-saving 8-pin SOIC (D) surface-mount package. Its key differentiator lies in its exceptionally low input bias current of typically 10nA, crucial for applications sensitive to input offset errors, such as high-impedance sensor interfacing. Operating from a ±2.25V to ±18V supply, or a single 5V to 36V supply, it maintains a low input offset voltage (typically 25µV) across this wide range. The device exhibits a unity-gain bandwidth of 1.2MHz and a slew rate of 0.8V/µs, suitable for moderate-speed signal processing._x000D_

Common applications include instrumentation amplifiers, precision voltage references, and low-noise signal conditioning circuits. The OPA171AIDBVR’s low input bias current and offset voltage minimize errors in high-impedance circuits, improving accuracy and stability. Its rail-to-rail capabilities maximize dynamic range, while its robust input protection ensures reliability even in noisy environments. The device’s low power consumption (typically 1.1mA at ±15V) further contributes to its suitability for battery-powered and portable applications. Engineers should consider this part when precise, low-noise amplification is paramount, particularly in applications with high-impedance sources and a need for wide supply voltage compatibility.
