elecTrical characTerisTics (V
CC = 2.5V, VDD = 2.5V, VEE = 0). The l denotes the specifications which
apply over the specified temperature range, otherwise specifications are at TA = 25°C. LE/HYST, SHDN pins floating, CL = 5pF,
VOVERDRIVE = 50mV, –IN = VCM = 300mV, +IN = –IN + VOVERDRIVE, 150mV step size unless otherwise noted.
