(AV_DD = DV_DD = 2.7V to 3.6V (MAX1041/MAX1043/MAX1047/MAX1049), external reference V_REF = 2.5V (MAX1041/MAX1043/
MAX1047/MAX1049), AV_DD = DV_DD = 4.75V to 5.25V (MAX1040/MAX1042/MAX1046/MAX1048), external reference V_REF = 4.096V
(MAX1040/MAX1042/MAX1046/MAX1048), 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 (MAX1041/MAX1043/MAX1047/MAX1049), AV_DD = DV_DD = 5V (MAX1040/MAX1042/
MAX1046/MAX1048), T_A = +25°C. Outputs are unloaded, unless otherwise noted.)
