Design Notes
Bypass the power supply pins with 0.1 µF ceramic capacitors placed as close as possible to the V+ and V- pins. Additionally, use a 10 µF tantalum capacitor in parallel for low-frequency decoupling. This ensures stable operation and minimizes noise coupling from the power supply.
For high-impedance inputs, use guard rings around the input pins to minimize leakage currents. The guard ring should be driven by a low-impedance source at the same potential as the input. This is especially important for photodiode amplifiers and other high-source-impedance applications.
Do not exceed the absolute maximum supply voltage of ±18 V. Also, ensure that the input voltages do not exceed the supply rails by more than 0.3 V, as specified in the datasheet. Exceeding these limits can damage the device.
