Mixed-signal chips
The 555 timer, ADC, DAC, VCO and other chips that mix analogue and digital.
| Part | Behaviour |
|---|---|
| 555 Timer | A timer for oscillators and one-shots. Set it up with resistors and a capacitor. |
| Monostable | Gives one pulse of a set length when triggered. |
| VCO | An oscillator whose frequency follows an input voltage. |
| Phase comparator | Compares the phase of two signals. |
| ADC | Turns an analogue voltage into a digital number. |
| DAC | Turns a digital number into an analogue voltage. |
Tips
- Give a 555 a clean supply and a decoupling capacitor, as on a real board.
- To test an ADC, vary the input with a slider and watch the digital outputs.
- Memory chips (RAM and ROM) are in Logic gates, digital chips and memory.
