OPA2241UA – TEXAS INSTRUMENTS

The Texas Instruments OPA2241UA is a precision, low-noise, low-drift operational amplifier packaged in a space-saving 8-lead SOIC (small outline integrated circuit) package. Operating from a ±15V to ±5V supply voltage range, it boasts a typical input offset voltage of only 25µV and a maximum input bias current of 10nA, crucial for applications demanding high accuracy. Its low input offset voltage drift of 0.2µV/°C ensures stable performance over temperature variations. The OPA2241UA features a unity-gain bandwidth of 4MHz and a slew rate of 2.8V/µs, suitable for moderately high-speed applications. Its low noise characteristics (1.8nV/√Hz at 1kHz) make it ideal for instrumentation and sensor amplification._x000D_

Common applications include precision signal conditioning, data acquisition systems, and low-level signal amplification where high accuracy and low drift are paramount. The device’s rail-to-rail output swing capability, although not fully rail-to-rail, maximizes dynamic range within the specified voltage range. Designers benefit from its excellent common-mode rejection ratio (CMRR) and low harmonic distortion, contributing to signal fidelity. However, its relatively low slew rate might limit its suitability for high-speed, high-bandwidth applications. Careful consideration of these specifications is essential for optimal circuit performance.
