7.1.1.4 Distortion Performance

The OPA695 provides good distortion performance into a 100-Ω load on ±5-V supplies. Compared to other devices, the OPA695 holds lower distortion at higher frequencies (> 20 MHz). Generally, until the fundamental signal reaches very high frequency or power levels, the 2nd-harmonic dominates the distortion with a negligible 3rd-harmonic component. Focusing on the 2nd-harmonic, increasing the load impedance directly improves distortion; the total load includes the feedback network. In the noninverting configuration (see Figure 6-1), this feedback network load is the sum of RF + RG, while in the inverting configuration, the feedback network load is only RF. Also, providing an additional supply decoupling capacitor (0.01 μF) between the supply pins (for bipolar operation) improves the 2nd-order distortion.
