Instructions for Use:

1. Power Supply: Ensure the supply voltage (Vcc) is within the specified operating range of 2.7V to 5.5V.
2. Biasing and Input Protection: The OPA2189IDR has very low input bias current. Proper biasing and protection networks should be used to avoid damage or performance degradation.
3. Noise Consideration: For applications sensitive to noise, consider the input voltage noise density of 9 nV/√Hz at 1kHz.
4. Stability: This amplifier is unity-gain stable. It can be used in applications requiring a wide range of gains without additional compensation.
5. Output Stage: The output voltage swing is ±3.8V with a load resistance of 10kΩ and a supply voltage of 5V. Ensure that the output does not exceed these limits to prevent distortion or damage.
6. Operating Temperature: While not listed in this table, ensure the device operates within its specified temperature range to maintain reliability and performance.

For detailed specifications and application notes, refer to the manufacturer's datasheet.
