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 DB0–DB15 and EOC. Inputs (CH0–CH7) 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. |
