ELECTRICAL CHARACTERISTICS (continued)
(VAVDD = +4.75V to +5.25V, VDVDD = +2.70V 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, fSAMPLE = 250ksps. 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 for more details.
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.
