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.)

See the Definitions section at the end of the data sheet.

Tested with alternating channels modulated at full scale and ground.

See the Input Range and Protection section for more details.

CLOAD = 30pF on DB0–DB15 and EOC. Inputs (CH0–CH7) alternate between full scale and zero scale. fCONV = 250ksps.

All data is read out.

Defined as the change in positive full scale caused by a ±2% variation in the nominal supply voltage.

It is recommended that RD, WR, and CS are kept high for the quiet time (tQ) and conversion time (tCON).

Guaranteed by design.
