Triple 8-bit ADC 170 Msps
Table 17: Characteristics…continued
VCCA = 4.75 V to 5.25 V (referenced to AGND); VCCD = 4.75 V to 5.25 V (referenced to DGND); VDDD = 4.75 V to 5.25 V
(referenced to VSSD); VCCO = 4.75 V to 5.25 V (referenced to OGND); AGND, DGND, OGND and VSS connected together;
Tamb = 0 to 70 °C; typical values measured at VCCA = VDDD = VCCD = VCCO = 5 V and Tamb = 25 °C; unless otherwise
specified.
