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 divided by R
L
.
The noise output voltage (RMS value) at f
i
= 500 kHz is measured with R
S
= 0
and bandwidth = 5 kHz.
20 Hz to 300 kHz (typical.
The ripple rejection is measured with R
S
= 0
and f = 100 Hz to 10 kHz. The ripple voltage (V
ripple
= 200 mV RMS)
is applied to the positive supply rail.
The channel unbalance is measured with V
DC1
= V
DC2
.
The channel unbalance at G
