181567fa

The q denotes the specifications which apply over the full operating

temperature range, otherwise specifications are at TA = 25°C (Note 8). VS = 5V, 0V; 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.
