Note 6. This value is measured at LOUT and ROUT pins using the circuit as shown in Figure 25.
Note 7. This value is the input impedance of an external device that the LOUT and ROUT pins can drive, when a device
is
included.
Note 8. Full scale (0dB) of the input voltage at ALC=OFF and IPGA=0dB.
Note 9. This value is input impedance of the IPGAL and IPGAR pins.
Note 10. This value is measured via the following path. Pre-Amp
Note 11. This value is the interchannel isolation between all the channels of the LIN1-5 and RIN1-5 when the applied
input
Note 12. PSR is applied to AVDD, DVDD and TVDD with 1kHz, 50mVpp.
Note 13. All digital input pins are held DVSS.

Normal Operation (PDN pin = “H”)
Power-down mode (PDN pin = “L”)
The input signal voltage is 2Vrms.
connected with LOUT and ROUT pin externally. The feedback resistor (min. 10k ) that it is usually connected
with the LOUT/ROUT pins, and the value of input impedance (min. 6.3k ) of the IPGAL/R pins are not
Input voltage to IPGAL and IPGAR pins is proportional to AVDD voltage. typ. Vin = 0.2 x AVDD (Vrms).
