LTC2609/LTC2619/LTC2629
ELECTRICAL CHARACTERISTICS The l denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. REFA = REFB = REFC = REFD = 4.096V (VCC = 5V), REFA = REFB =
REFC = REFD = 2.048V (VCC = 2.7V). REFLO = 0V, VOUT = unloaded, unless otherwise noted.
