Stand-Alone, 10-Channel, 12-Bit System Monitors
with Internal Temperature Sensor and V_DD Monitor
ELECTRICAL CHARACTERISTICS (continued)
(V_DD = +2.7V to +3.6V (MAX1253), V_DD = +4.5V to +5.5V (MAX1254), V_REF = +2.5V (MAX1253), V_REF = +4.096V (MAX1254), f_SCLK
= 10MHz (50% duty cycle), T_A = T_MIN to T_MAX, unless otherwise noted. Typical values are at T_A = +25°C.)
