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 divided by R_L.
2. The noise output voltage (RMS value) is measured with R_S = 5 kΩ unweighted (20 Hz to 20 kHz).
3. The noise output voltage (RMS value) at f = 500 kHz is measured with R_S = 0 Ω and bandwidth = 5 kHz.
With a practical load (R_L = 16 Ω, L_L = 200 µH) the noise output current is only 50 nA.
4. The ripple rejection is measured with R_S = 0 Ω and f = 100 Hz to 10 kHz.
The ripple voltage (200 mV) is applied to the positive supply rail.
5. R_S = 5 kΩ.
