ELM403 Datasheet (ELM) - Rotary Decoder

ELM403, Rotary Decoder

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
