CS3310
Figure 7 is a 16k FFT plot demonstrating the crosstalk performance of the CS3310 at 20 kHz.
Both channels were set to unity gain. The right channel input is grounded with the left channel
driven to 2.65 Vrms output at 20 kHz. The FFT plot is of the right channel output. This indicates
channel to channel crosstalk of -130 dB at 20 kHz.
Figure 10 is a series of plots which display the unity-gain THD+N vs. Frequency for 600 Ω, 2 kΩ
and infinite load conditions. The output was set to 2 Vrms. The Audio Precision System One was
bandlimited to 22 kHz
Figure 11 is a series of plots which display the unity-gain THD+N vs. Frequency for 1, 2 and 2.8
Vrms output levels. The output load was open circuit. The Audio Precision System One was
bandlimited to 22 kHz.
