specified.
Notes
1. The low frequency power roll-off is determined by the value of the electrolytic lift capacitors.
2. The low frequency gain roll-off is determined by the value of the input coupling capacitors.
3. Supply voltage ripple rejection is measured across R
4. Common mode rejection ratio is measured across R
5. Input signal rejection ratio is measured across R
6. Noise output voltage is measured in a bandwidth of 20 Hz to 20 kHz.
7. Noise output voltage is independent of source impedance R
