Linear Technology 

LTC1650

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

temperature range, otherwise specifications are at TA = 25°C. AVDD = 4.75V to 5.25V, AVSS = – 4.75V to – 5.25V, DVDD = 4.75V to

5.25V, REFLO = 0V, REFHI = 4.096V, VOUT unloaded, unless otherwise noted.
