Notes: 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 RL.
2. The noise output voltage (RMS value) is measured with RS=5k
Ω unweighted.
3. The noise output voltage (RMS value) at f=500kHz is measured with RS=0
Ω and bandwidth=5kHz.
4. The ripple rejection is measured with RS=0
Ω and f=100Hz~10kHz. The ripple voltage of 200mV, (RMS
value) is applied to the positive supply rail.
