Note 2:
Supply current is tested with COMPIN+ = (REF – 100mV) for LTC1541 and COMPIN+ = 0V, COMPIN– = 100mV for LTC1542.
Note 7:
The LTC1541C/LTC1541I and LTC1542C/LTC1542I are guaranteed functional over the operating temperature range of –40
Note 3:
Input offset voltage is defined as the center of the input referred °C to 85 hysteresis, V °C. CM = REF (LTC1541). VCM = 1/2 VCC (LTC1542).
Note 8:
The LTC1541C and LTC1542C are guaranteed to meet specified
Note 4:
Trip point is defined as the differential input voltage required to performance from 0 make the comparator output change state. The difference between upper °C to 70°C. The LTC1541C and LTC1542C are designed, characterized and expected to meet performance from –40 and lower trip point is equal to the width of the input referred hysteresis, °C to 85 V °C, but are not tested or QA sampled at these temperatures. The CM = REF (LTC1541). VCM = 1/2 VCC (LTC1542). LTC1541I and LTC1542I are guaranteed to meet specified performance
Note 5:
The input leakage current is measured for COMPIN+ at 0V from –40°C to 85°C. (LTC1541) and COMPIN+ = COMPIN– = 0V (LTC1542).
