Other Parts Discussed in Thread: LM211

Hello,

Customer want to know the power consumption of LM211 with input signal frequency has variation.

I think that it has lower power consumption when lower frequency signal inputs.

Please give some data for power consumption or any calculation method.

Beast Regards.

There is no available data at different input signal frequency. In general the frequency affects the power dissipation because of presence current and voltage in a circuit and because of gate charge (switching power supply for example). If we look at the LM211 intenal circuit. It is bipolar so gate charge is very low and there is a limiting resistor in each branch. I do not expect big differnce with higher frequency. We can do bench test for confirmation.
