ELECTRICAL CHARACTERISTICS The l denotes the specications which apply over the temperature range
–40°C < TA < 85°C (LT6105I), otherwise specications are at TA = 25°C. V+ = 12V, V– = 0V, VS+ = 12V (see Figure 1), RIN1 = RIN2 =
100
Ω, ROUT = 5k (AV = 50), VSENSE = VS+ – VS–, unless otherwise specied. (Note 5)
