The OPA211IDRGT is a precision operational amplifier from Texas Instruments, designed for low noise and low power applications. It features a low voltage noise density of 1.1 nV/,àöHz at 1 kHz and an input voltage noise of 80 nV_PP over a frequency range of 0.1 to 10 Hz. The amplifier has a total harmonic distortion plus noise (THD+N) of -136 dB at a gain of 1 and a frequency of 1 kHz. It offers a maximum offset voltage of 125 OºV and a typical offset voltage drift of 0.35 OºV/¬8C. The OPA211IDRGT operates with a low supply current of 3.6 mA per channel and is unity-gain stable. It has a gain bandwidth product of 80 MHz and a slew rate of 27 V/Oºs, making it suitable for high-speed applications. The device supports a wide supply voltage range from ¬±2.25 V to ¬±18 V or from 4.5 V to 36 V for single-supply operation. It provides rail-to-rail output and can deliver an output current of up to 30 mA. This operational amplifier is available in multiple package options, including SON-8, VSSOP-8, and SOIC-8, and is specified for operation over a temperature range of -40¬8C to +125¬8C. The OPA211IDRGT is suitable for various applications, including data acquisition systems, ultrasound scanners, and precision instrumentation.
