The Rotary Decoders are Here

There’s been a fair bit of interest in converting signals from quadrature encoders, so we’ve added 8 new ICs to the lineup. These provide several processing options, from simply debouncing, to conversion to two or three wire serial signals with 2x or 4x decoding. Sorry, no SPI at this time.

Here’s the new lineup. For more information, visit the ‘electronics bench‘ products section, or click on the individual chip:

ELM401 Rotary Encoder Debounce Circuit
ELM402 Rotary Decoder – 2 wire 2x Interface
ELM403 Rotary Decoder – 2 wire 4x Interface
ELM404 Rotary Decoder – 3 wire 2x Interface
ELM405 Rotary Decoder – 3 wire 4x Interface
ELM406 Rotary Decoder – 3 wire 2x Interface
ELM407 Rotary Decoder – 3 wire 4x Interface
ELM408 Rotary Decoder – 2 wire Interface
