PCB Layout Examples
- Simon Says - Tilt!
- EIT - Tristate Buffer Decoder Circuit (16-to-2)
- A circuit which employs 8 Tristate Buffer chips to demux 16 incoming electrode connections to 2 outputs for the ADC; has better speed, noise, and impedance characteristics, at the expense of added complexity and cost.
- EIT - Multiplexer Circuit (16-to-2)
- A circuit which employs 4 multiplexing chips to demux 16 incoming electrode connections to 2 outputs for the ADC; less expensive and less complicated than the previous example, but also is slightly lower performance.
