Notes to the characteristics
1. The unweighted RMS noise output voltage is measured at a bandwidth of 60 Hz to 15 kHz with a source impedance
(R_S) of 5 kΩ.
2. The RMS noise output voltage is measured at a bandwidth of 5 kHz with a source impedance of 0 Ω and a frequency
of 500 kHz. With a practical load (R = 8 Ω; L = 200 µH) the noise output current is only 100 nA.
3. Ripple rejection is measured at the output with a source impedance of 0 Ω and a frequency between 100 Hz and
10 kHz. The ripple voltage = 200 mV (RMS value) is applied to the positive supply rail.
