LT1815/LT1816/LT1817
ELECTRICAL CHARACTERISTICS The
l
denotes the specifi cations which apply over the full operating temp- erature range, otherwise specifi cations are at TA = 25°C (Note 8). VS = 5V, OV; VCM = 2.5V, RL to 2.5V, unless otherwise noted. For the programmable current option (LT1815S6 or LT1816A), the ISET pin must be connected to V– through 75Ω or less, unless otherwise noted. SYMBOL PARAMETER CONDITIONS MIN TYP MAX UNITS
