LTC6603
ELECTRICAL CHARACTERISTICS The l denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. V+A = V+D = V+IN = 3V, VICM = VOCM = 1.5V, Gain = 0dB, lowpass cutoff =
2.5MHz, internal clocking with RBIAS = 30.9k unless otherwise noted.
