[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 R_L.
[2] Power supply rejection ratio is measured at the output with a source impedance of R_S = 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.
[3] Power supply rejection ratio is measured at the output, with a source impedance of R_S = 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.
