Temperature Sensor Gain Factor

mV/°C

Five diodes in series

1 1 μs period, pulse width = 50 ns to 500 ps, pulse width measured when amplitude drops 10%.

2 Measured at 50% of input amp to 50% of output amp.

3 tPD measured from the 50% of enable signal to 50% of output.

4 The low leakage mode of the comparator, controlled by VLLM input, reduces the leakage due to the comparator input. The comparator operates in this mode, but its

bandwidth is compromised and is not guaranteed.

5 Under no circumstances should the input voltages exceed the supply voltages.
