OPA177GS General Description

The OPA177GS is a precision operational amplifier manufactured by Texas Instruments. It features low offset voltage, low input bias current, and low noise, making it suitable for applications requiring high accuracy and stability. With a unity-gain bandwidth of typically 5 MHz and a slew rate of typically 5 V/µs, it can handle fast signal processing tasks. The OPA177GS operates over a wide supply voltage range, typically ±2.25 V to ±18 V, making it versatile for various power supply configurations. Its input offset voltage is typically 25 µV, ensuring minimal error in precision applications. The device is available in a small outline surface mount package (SOIC), enabling easy integration into compact designs. It is commonly used in instrumentation, data acquisition, and sensor signal conditioning applications where precision and reliability are critical.
