Overview
ELM403 Rotary Decoder - 2 wire 4x Interface
Description
The ELM403 is an 8 pin integrated circuit that is used to convert the signals from a rotary encoder into a series of up and down output pulses.
The low power CMOS technology used ensures that only a very small current is required over the entire 2.
0 to 5.
5 volt operating range.
There is no need for external filtering or debounce circuits with the ELM403, as this is all performed within the integrated circuit.
After debouncing the encoder signals, the ELM403 then determines the direction of shaft rotation, and generates the appropriate pulses at the Up or Down output pins.
The duration of these pulses can be selected for either 0.
2 or 2.
