Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: For the LTC1470, the two output pins (1, 8) must be connected
together and the two 3.3V supply input pins (6 , 7) must be connected
together. For the LTC1471, the two AOUT pins (1, 16) must be connected
together, the two BOUT pins (8, 9) must be connected together, the two

B3V
pins (5, 13) must be connected together.
Note 3: Power for the input logic and charge pump circuitry is derived
from the 5V

Note 4: Measured current is per channel with the other channel
programmed off for the LTC1471.
Note 5: The output is protected with foldback current limit which reduces
the short-circuit (0V) currents below peak permissible current levels at
higher output voltages.
Note 6: To 90% of final value.
Note 7: The LTC1470 is guaranteed to meet performance specifications
from 0°C to 70°C. Specifications over the –40°C to 85°C operating
temperature range are assured by design, characterization and correlation
with statistical process controls.
