LTC6246/LTC6247/LTC6248
ELECTRICAL CHARACTERISTICS (VS = 2.7V) The
l
denotes the specifications which apply across the specified temperature range, otherwise specifications are at TA = 25°C. For each amplifier VS = 2.7V, 0V; VSHDN = 2V; VCM = VOUT = 1.35V, unless otherwise noted. SYMBOL PARAMETER CONDITIONS MIN TYP MAX UNITS
