Note 1: Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2: Supply current is tested with COMPIN
LTC1541 and COMPIN
Note 3: Input offset voltage is defined as the center of the input referred
hysteresis, V
Note 4: Trip point is defined as the differential input voltage required to
make the comparator output change state. The difference between upper
and lower trip point is equal to the width of the input referred hysteresis,
V
Note 5: The input leakage current is measured for COMPIN
(LTC1541) and COMPIN

Note 6: The θ
spreading metal. Using expanded metal area on all layers of a board
reduces this value.
Note 7: The LTC1541C/LTC1541I and LTC1542C/LTC1542I are
guaranteed functional over the operating temperature range of –40°C to
85°C.
Note 8: The LTC1541C and LTC1542C are guaranteed to meet specified
performance from 0°C to 70°C. The LTC1541C and LTC1542C are
designed, characterized and expected to meet performance from –40°C to
85°C, but are not tested or QA sampled at these temperatures. The
LTC1541I and LTC1542I are guaranteed to meet specified performance
from –40°C to 85°C.
