LTC4260 Linear Technology, LTC4260 Datasheet - Page 5

• Manufacturer Part Number: LTC4260
• Description: Positive High Voltage Hot Swap Controller
• Manufacturer: Linear Technology

ELECTRICAL CHARACTERISTICS
Note 3: Limits on maximum rating is defined as whichever limit occurs
first. An internal clamp limits the GATE pin to a minimum of 10V above
source. Driving this pin to voltages beyond the clamp may damage the
device.
Note 4: Guaranteed by design and not subject to test.
Note 5: Integral nonlinearity is defined as the deviation of a code from a
precise analog input voltage. Maximum specifications are limited by the
LSB step size and the single shot measurement. Typical specificatons are
measured from the 1/4, 1/2 and 3/4 areas of the quantization band.

Note 6: 1LSB step size specification is guaranteed by full-scale voltage
measurement and by design.
Note 7: Full-scale current sense specification corresponds to code 200.
Codes above 200 may be discarded by offset cancellation.
