In this session of Logic Noise, we’ll be playing around with the voltage-controlled oscillator from a 4046 phase-locked loop chip, and using it to make “musical” pitches. It’s a lot of ...

A successive approximation register ADC works by quickly cycling through all possible voltage levels in its ... of easily sourced analogs for the sample-hold and comparator section.

The ADC includes internal sample/hold circuits, a capacitive DAC, a comparator, and logic control circuits. External reference voltage is needed. The voltage reference input can be adjusted to allow ...
