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