Design Notes
For optimal performance, use 0.1 µF ceramic capacitors close to the V+ and V- pins to decouple the power supply. Additionally, a 10 µF tantalum capacitor can be used for bulk decoupling. Proper decoupling reduces power supply noise and ensures stable operation.
Keep the input traces short and shielded to minimize noise pickup. Use a ground plane under the op amp to reduce parasitic capacitance and improve CMRR. Avoid routing high-speed digital traces near the input pins to prevent interference.
Do not exceed the absolute maximum supply voltage of ±18 V. Also, ensure the input voltages do not exceed the supply rails. The output can drive capacitive loads over 100 pF, but for larger loads, add a series resistor to maintain stability.
