Note 4. This value is measured at LOUT and ROUT pins using the circuit as shown in Figure 24.
The input signal voltage is 2Vrms.
Note 5. This value is the input impedance of an external device that the LOUT and ROUT pins can drive, when a device is
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 included.
Note 6. Full scale (0dB) of the input voltage at ALC=OFF and IPGA=0dB.
Input voltage to IPGAL and IPGAR pins is proportional to AVDD voltage. Vin = 0.2 x AVDD (Vrms).
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
→
IPGA (Gain : 0dB)
→
ADC.
The measurement circuit is Figure 24.
Note 9. This value is the interchannel isolation between all the channels of the LIN1-5 and RIN1-5 when the applied input
signal causes the Pre-Amp output to equal IPGA input.
Note 10. PSR is applied to AVDD and DVDD with 1kHz, 50mVpp.
Note 11. All digital input pins are held DVDD or DVSS.
