10-Bit Serial-Output Temperature Sensors
with 5-Channel ADC
ELECTRICAL CHARACTERISTICS (continued)
(V_DD = +4.75V to +5.25V (MAX1098), V_DD = +2.7V to +3.6V (MAX1099), external reference, V_REF = +2.5V (MAX1098), V_REF = +1.2V
(MAX1099), f_SCLK = 2.5MHz, T_A = T_MIN to T_MAX, unless otherwise noted. Typical values are at T_A = +25°C.)
