8.2.3 Application Curves
The THD+N performance for the circuit described in the Excitation Voltage section is measured for a 10-kHz, 10-VPP output signal from each op-amp channel. These measurement results are displayed in Table 8-2.
Table 8-2 Maximum Output Power and THD+N
| LOAD IMPEDANCE (Ω) | MAXIMUM OUTPUT POWER (mW) | THD+N AT MAXIMUM OUTPUT POWER (dB) |
|---|---|---|
| 100 | 292 | –50 |
Figure 8-4 shows the THD+N performance for different input signal frequencies with a measurement bandwidth of 80 kHz. Figure 8-5 shows the circuit response with load capacitances of up to 100 nF. Using a larger resistor in series with the output, as shown in Section 8.1.1 further improves phase margin.
