LTC1992 Family
ELECTRICAL CHARACTERISTICS The
l
denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C. +VS = 5V, –VS = 0V, VINCM = VOUTCM = VOCM = 2.5V, unless otherwise noted. VOCM is the voltage on the VOCM pin. VOUTCM is defined as (+VOUT + –VOUT)/2. VINCM is defined as (+VIN + –VIN)/2. VINDIFF is defined as (+VIN – –VIN). VOUTDIFF is defined as (+VOUT – –VOUT). Typical values are at TA = 25°C. Specifications apply to the LTC1992-5 only. LTC1992-5CMS8 LTC1992-5ISM8 LTC1992-5HMS8 SYMBOL PARAMETER CONDITIONS MIN TYP MAX MIN TYP MAX UNITS
