LTC1451
LTC1452/LTC1453
ELECTRICAL CHARACTERISTICS The q denotes specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. VCC = 4.5V to 5.5V (LTC1451), 2.7V to 5.5V (LTC1452/LTC1453),
internal or external reference (VREF ≤ VCC/2), VOUT and REF unloaded, unless otherwise noted.
