OPA211IDR

The OPA211IDR from Texas Instruments is a high-performance, low-power operational amplifier designed for precision applications. It boasts an impressive input voltage noise of 1.1 nV/√Hz at 1 kHz and a typical gain bandwidth product of 45 MHz (G=1), extending to 80 MHz (G=100).

This amplifier operates over a wide supply voltage range of ±2.25 V to ±18 V or 4.5 V to 36 V. It features a low offset voltage of 0.05 mV maximum at 25°C and a low offset drift of 0.15 µV/°C typical. The OPA211IDR also provides a slew rate of 27 V/µs and a settling time of 700 ns for 16-bit accuracy.

Designed for versatility, the OPA211IDR includes features like shutdown capability and a small size. It offers rail-to-rail output swing and a typical output current of 30 mA. The device is available in multiple package options including WSON-8 (3 mm × 3 mm), VSSOP-8, and SOIC-8, making it suitable for various surface-mount designs.

With its combination of low noise, low power consumption, and high precision, the OPA211IDR is well-suited for demanding applications in audio, instrumentation, and general-purpose analog circuit design.
