LT1719
ELECTRICAL CHARACTERISTICS The
l
denotes the specifi cations which apply over the full operating temperature range, otherwise specifi cations are at TA = 25°C. VCM = 1V, VSHDN = 0.5V, VOVERDRIVE = 20mV, COUT = 10pF and for the LT1719S8 VCC = +VS = 5V and VEE = –5V, for the LT1719S6 V+ = 5V, V– = 0V, unless otherwise specifi ed.
