ELECTRICAL CHARACTERISTICS (continued)
VAVDD = 4.75V to 5.25V, VDVDD = +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: Tested with alternating channels modulated at full scale and ground.
Note 3: See the Input Range and Protection section.
Note 4: CLOAD= 30pF on DB0–DB15 and EOC. Inputs (CH0–CH7) alternate between full scale and zero scale. fCONV = 250ksps. All
data is read out.
Note 5: Defined as the change in positive full scale caused by a ±2% variation in the nominal supply voltage.
Note 6: It is recommended that RD, WR, and CS are kept high for the quiet time (tQ) and conversion time (tCON).
Note 7: Guaranteed by design.
Typical Operating Characteristics
(VAVDD = 5V, VDVDD = 3.3V, TA = +25°C, fSAMPLE = 250ksps, internal reference, unless otherwise noted.)
