Notes to the characteristics
1. With a load connected to the outputs the quiescent current will increase, the maximum value of this increase being
equal to the DC output offset voltage dividend by R_L.
2. The noise output voltage (RMS value) at f = 500 kHz is measured with R_S = 0 Ω and bandwidth = 5 kHz.
3. The ripple rejection is measured with R_S = 0 Ω and f = 100 Hz to 10 kHz. The ripple voltage of 200 mV, (RMS value)
is applied to the positive supply rail.
4. The noise output voltage (RMS value) is measured with R_S = 5 kΩ unweighted.
