Linear Technology 

LTC1595/LTC1596/LTC1596-1

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

temperature range, otherwise specifications are at TA = 25°C. VDD = 5V ±10%, VREF = 10V, VOUT1 = VOUT2 = AGND = 0V, TA = TMIN to

TMAX, unless otherwise noted.
