The supply voltage range at pin V
Measured with low-pass filter 30 kHz.
Noise output voltage measured with a bandwidth of 20 Hz to 20 kHz, unweighted. R
RMS output voltage in mute is measured with V
DC output offset voltage is measured between the signal output and the 0.5V
The ripple rejection is measured with a ripple voltage of 200 mV (RMS) applied to the positive supply rail (R
DC output offset voltage is measured between the two signal outputs.
