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 =
300kHz, highpass cutoff = 45kHz, internal clocking with RBIAS = 54.9k unless otherwise noted.
