Other Parts Discussed in Thread: TLE2064, TLE2062
I am using TLE2064 in my design. We find a strange issue during the test. When TLE2064 is working as a comparator (shown in the schematic, i.e. non-inverting input is connected to GND and inverting input is connected to an input, and there is no load on the output). When the input increases from 0V to +0.6V, the current of +12V and -12V power supply increases with the amplitude, and the maximum is 8mA. But when the input decreases from 0V to-0.6V, the current of +12V and -12V power supply remains unchanged.
It seems there is some current flow inside TLE2064 from +12V to -12V when the input is from 0V to +0.6V. Is this because of the internal characteristic of TLE2064?
