OP2244UA – TEXAS INSTRUMENTS

The OP2244UA is a dual, low-power, precision operational amplifier from Texas Instruments, packaged in a space-saving 8-pin SOIC (small outline integrated circuit). It operates from a ±2.25V to ±18V supply voltage range, exhibiting a low input bias current of typically 2nA and a very low input offset voltage of ±20µV (max). This ensures high accuracy and stability in applications requiring minimal drift. The device features a high common-mode rejection ratio (CMRR) of typically 100dB, minimizing the impact of common-mode noise. Its low noise density, typically 7.5nV/√Hz, makes it suitable for precision instrumentation and signal conditioning._x000D_

The OP2244UA’s rail-to-rail output swing capability, although not fully rail-to-rail, extends close to the supply rails, maximizing output signal amplitude. Common applications include precision instrumentation amplifiers, low-noise data acquisition systems, and sensor interfaces where high accuracy, low power consumption, and stability are crucial. Its inherent low offset voltage and drift significantly reduce the need for external compensation or trimming, simplifying circuit design and reducing component count. The device’s robust performance across a wide temperature range makes it suitable for both industrial and automotive applications. Its low power consumption contributes to extended battery life in portable devices.
