Note 2. Measured with two superimposed signals of 50Hz and 7kHz with an amplitude relationship

of 4:1.

Note 3. The closed loop gain is determined by external resistors and is variable between 20dB and

46dB.

Note 4. The input impedance is determined by the bias resistor.

Note 5. The noise output voltage is measured in a bandwidth of 20Hz to 20kHz with a source resist-

ance of 2kΩ.

Note 6. The quiescent current into Pin2 has an impact on the mute time.
