Note 3: 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,
VCM = REF (LTC1541). VCM = 1/2 VCC (LTC1542).
Note 4: The input leakage current is measured for COMPIN+ at 1.5V
(LTC1541) and COMPIN+ = COMPIN– = 1.5V (LTC1542).

Note 1: Supply current is tested with COMPIN+ = (REF – 100mV) for
LTC1541 and COMPIN+ = 0V, COMPIN– = 100mV for LTC1542.
Note 2: Input offset voltage is defined as the center of the input referred
hysteresis, VCM = REF (LTC1541). VCM = 1/2 VCC (LTC1542).
