(1) Analog Characteristics
1-1) ADC
(Ta=25°C; AVDD=DVDD=3.3V; DVDD18=1.8V, VREFH=AVDD, VREFL=VSS1, BITCLK=64fs; Signal frequency
1kHz; Measurement frequency=20Hz~20kHz@48kHz, 20Hz~40kHz@96kHz; ADC full differential input (ADC1,
ADC2); CKM Mode 0 (CKM[2:0]=000), during SRC reset, unless otherwise specified.)
Note 11. Values are not guaranteed with single-ended inputs.
Note 12. S/(N+D) when -60dB signal is applied.
Note 13. Inter-channel isolation between L-channel and R-channel at –1dBFS signal input.
Note 14. AINL+, AINL-, AINR+, and AINR- pins.
Note 15. AINL2~L8, and AINR2~R8 pins.
Note 16. AINL+, AINL-, AINR+, AINR-, AINL2~L8, and AINR2~R8 pins.
Note 17. AINM pin. The full scale of input voltage is (FS=(VREFH-VREFL) x (2.0/3.3)).
Note 18. AINM pin.
