Note : 5. Analog input voltage (full-scale voltage: IPGA = 0dB) scale with VREF. (IPGA = ADC = 0.6 x VREF.)
Note : 6. ADC is input from LIN1/RIN1 or LIN2/RIN2 and it measures included in IPGA. The value of IPGA is set 0dB.
Note : 7. Analog output voltage scale with VREF. (DAC = 0.6 x VREF.)
Note : 8. Input: OPGAL/OPGAR; Output: LOUT2/ROUT2; OPGA = 0dB.
Note : 9. Noise level when reference voltage is 1.5Vpp.
Note : 10. Analog input/output voltage scale with VREF. (OPGA = 0.6 x VREF.)
MS0031-E-00
unless otherwise specified)
Internal HPF cancels the offset of IPGA and ADC.
