Notes
1.
The noise output voltage is measured at the output in a frequency band from 20 Hz to 20 kHz (unweighted),
R
source
= 0
, gain select pin is LOW (0 V).
Supply voltage ripple rejection is measured at the output, with a source impedance of R
source
= 0
at the input.
The ripple voltage is a sine wave with a frequency of 1 kHz and an amplitude of 100 mV (RMS) is applied to the
positive supply rail, gain select pin is LOW (0 V).
