Minimum load requirements for the HF73 with voltage outputs
The following requirements apply to any external device or circuit connected to the HF73 transmitter with voltage outputs:
In the situation where the external device uses an internal pull-up resistor the value of this resistor should meet the requirements shown below. It is also necessary to add a pull-down resistor RL connected to ground in order to be able to read 100% of the range of the HF73 voltage output.
