[1] With a load connected at the outputs the quiescent current will increase, the maximum of this increase being equal to the DC output
offset voltage divided by RL.
[2] The DC output voltage with respect to ground is approximately 0.5 × VCC.

[1] Gain of the amplifier is 2 × (R2 / R1) in test circuit of Figure 3.
[2] The noise output voltage is measured at the output in a frequency range from 20 Hz to 20 kHz (unweighted), with a source impedance
of RS = 0 Ω at the input.
[3] Supply voltage ripple rejection is measured at the output with a source impedance of Rs = 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), which is applied to the positive supply rail.
[4] Supply voltage ripple rejection is measured at the output, with a source impedance of Rs = 0 Ω at the input. The ripple voltage is a
sine wave with a frequency between 100 Hz and 20 kHz and an amplitude of 100 mV (RMS), which is applied to the positive supply rail.
[5] Output voltage in mute position is measured with an input voltage of 1 V (RMS) in a bandwidth of 20 kHz, which includes noise.
