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. 2 KKA7052 N SUFFIX PLASTIC DIP (MS – 001BA) A Dimension, mm 5 8 B 1 4 MIN MAX A 8.51 10.16 B 6.1 7.11 5.33 C L F Symbol C D 0.36 0.56 F 1.14 1.78 -T- SEATING PLANE N G K D 0.25 (0.010) M M H J T NOTES: 1.
