PRODUCTION DATA.
The use of supply decoupling is mandatory in most applications. As with most relatively high-speed or high-output current op amps, best results are achieved when each supply line is decoupled with two capacitors; a small value ceramic capacitor ( about 0.01 μF) placed very close to the supply lead in addition to a large value Tantalum or Aluminum (> 4.7 μF). The large capacitor can be shared by more than one device if necessary. The small ceramic capacitor maintains low supply impedance at high frequencies while the large capacitor will act as the charge bucket for fast load current spikes at the op amp output. The combination of these capacitors will provide supply decoupling and will help keep the op amp oscillation free under any load.
