OPA134UA – TEXAS INSTRUMENTS

The Texas Instruments OPA134UA is a precision, low-noise, single-supply operational amplifier packaged in a small, space-saving SOIC-8 package. Operating from a single supply voltage of 2.7V to 5.5V, it boasts a typical input offset voltage of only 25µV and a low input bias current of 10nA, making it ideal for applications requiring high accuracy and minimal drift. Its low noise voltage density of 18nV/√Hz ensures clean signal amplification, even at low frequencies._x000D_

The OPA134UA features a wide gain bandwidth product of 1.3MHz and a slew rate of 0.7V/µs, suitable for moderate-speed signal processing. Its rail-to-rail output swing, extending almost to the supply rails, maximizes dynamic range. Common applications include instrumentation amplifiers, sensor signal conditioning (particularly with low-level signals), and precision analog filters in battery-powered systems._x000D_

A key advantage is its ability to operate from a single supply, simplifying circuit design and reducing component count. The low input offset voltage and bias current contribute to superior accuracy and stability, minimizing the need for frequent calibration or trimming. Its small package size further enhances its suitability for space-constrained designs where high performance is paramount.
