Note 4. This value is measured at LOUT and ROUT pins using the circuit as shown in Figure 24.
Note 5. This value is the input impedance of an external device that the LOUT and ROUT pins can drive, when a device is
Note 6. Full scale (0dB) of the input voltage at ALC=OFF and IPGA=0dB.
Note 7. This value is input impedance of the IPGAL and IPGAR pins.
Note 8. This value is measured via the following path. Pre-Amp
Note 9. This value is the interchannel isolation between all the channels of the LIN1-5 and RIN1-5 when the applied input
Note 10. PSR is applied to AVDD and DVDD with 1kHz, 50mVpp.
Note 11. All digital input pins are held DVDD or DVSS.
