Notes

1. Volume setting at maximum.

2. The noise output voltage is measured at the output in a frequency band from 20 Hz to 20 kHz (unweighted),

Rsource = 0 Ω, gain select pin is LOW (0 V).

3. Supply voltage ripple rejection is measured at the output, with a source impedance of Rsource = 0 Ω at the input.

The ripple voltage is a sine wave with a frequency of 1 kHz and an amplitude of 100 mV (RMS) is applied to the

positive supply rail, gain select pin is LOW (0 V).

4. Channel suppression is measured at the output with a source impedance of Rsource = 0 Ω at the input and a

frequency of 1 kHz. The output level in the operating single-ended channel (OUT+) is set at 2 V (RMS).
