LTC6373
ELECTRICAL CHARACTERISTICS The
l
denotes the specifications which apply over the full operating temperature range, otherwise specifications and all typical values are at TA = 25°C. V+ = V+OUT = 15V, V– = –15V, VICM = VOCM = DGND = 0V, G = 1 (A2 = 5V, A1 = A0 = 0V). VS is defined as (V+ – V–). VICM is defined as (V+IN + V–IN)/2. VOUTCM is defined as (V+OUT + V–OUT)/2. VOUTDIFF is defined as (V+OUT – V–OUT). SYMBOL PARAMETER CONDITIONS MIN TYP MAX UNITS
