Amplifier’s output impedance: Rout < 5 Ω.
Amplifier’s input impedance: Rout ≥ 10 kΩ.
Audio input’s signal amplitude: Vin,RMS = 0.3 V (nominal), Vin,max = 1 V (peak-to-peak).
Audio input’s source impedance: Rsig = 100 Ω.
3-dB small-signal bandwidth: 18Hz-25kHz (nominal).
Full-power bandwidth: >20kHz.
Total harmonic distortion: THD<0.1% or -60dB with Pout,RMS = 100 mW on nominal load RL = 32Ω at 1kHz.
