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

 and bandwidth = 5 kHz.

3. The ripple rejection is measured with R

S

 = 0

 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 k

 unweighted.
