 +  * **Dual vs. Single Supply:** While it can operate on a single supply (4.6V to 36V), using a dual supply (±2.3V to ±18V) is recommended to ensure the output can swing fully to zero.
 +  * **REF Pin:** Do not leave this pin floating. Tie it to GND for a 0V reference or to a specific voltage if you need to level-shift the output.
 +  * **Decoupling:** Always place bypass capacitors (e.g., 0.1µF) between the supply pins and ground to minimize noise.
