(AV_DD = DV_DD = 2.7V to 3.6V (MAX1021/MAX1023/MAX1057), external reference V_REF = 2.5V (MAX1021/MAX1023/MAX1057), AV_DD =
DV_DD = 4.75V to 5.25V (MAX1020/MAX1022/MAX1058), external reference V_REF = 4.096V (MAX1020/MAX1022/MAX1058), f_SCLK = 4.8MHz
(50% duty cycle), T_A = -40°C to +85°C, unless otherwise noted. Typical values are at AV_DD = DV_DD = 3V (MAX1021/MAX1023/MAX1057),
AV_DD = DV_DD = 5V (MAX1020/MAX1022/MAX1058), T_A = +25°C. Outputs are unloaded, unless otherwise noted.)
