ELECTRICAL CHARACTERISTICS The l denotes the speciﬁcations which apply over the full operating temp-

erature range, otherwise speciﬁcations 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.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings

may cause permanent damage to the device. Exposure to any Absolute

Maximum Rating condition for extended periods may affect device

reliability and lifetime.

Note 2: Differential inputs of ±6V are appropriate for transient operation

only, such as during slewing. Large sustained differential inputs can cause

excessive power dissipation and may damage the part.
