Simultaneous-Sampling ADCs
ELECTRICAL CHARACTERISTICS (continued)
(AVDD = 4.75V to 5.25V, DVDD = +2.7V to 5.25V, VAGNDS = VAGND = VDGND = 0V, VREFIO = internal reference, CRDC = 4 x 33μF,
CREFIO = 0.1μF, CAVDD = 4 x 0.1μF || 10μF, CDVDD = 3 x 0.1μF || 10μF; all digital inputs at DVDD or DGND, unless otherwise noted.
TA = -40°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C.)
Note 1: See the Definitions section at the end of the data sheet.
Note 2: Guaranteed at 5V ⤠VAVDD ⤠5.25V for+25°C ⤠TA ⤠+85°C. See the Input Range and Protection section and Typical
Operating Characteristics.
Note 3: TA = -40°C.
Note 4: Dynamic performance is guaranteed at AVDD = 5.0V to 5.25V. See the Input Range and Protection section and the Typical
Operating Characteristics.
Note 5: Tested with alternating channels modulated at full scale and ground.
Note 6: See the Input Range and Protection section.
Note 7: CLOAD= 30pF on DB0âDB15 and EOC. Inputs (CH0âCH7) alternate between full scale and zero scale. fCONV = 250ksps. All
data is read out.
Note 8: Defined as the change in positive full scale caused by a ±2% variation in the nominal supply voltage.
Note 9: It is recommended that RD, WR, and CS are kept high for the quiet time (tQ) and conversion time (tCON).
Note 10: Guaranteed by design.
