What it represents
Provides a reference voltage through a series-connected supply and output arrangement.
On a schematic, identify the input supply, reference output and reference return and trace the ADC/DAC reference network and any buffering. Keep the component tag and signal/reference names consistent across the control drawing, terminal schedule and device documentation.
A reference establishes a measurement datum; it is not automatically a load-power regulator.
The preview is an independently drawn educational functional reference. Add the selected component’s actual power pins, terminal numbers, timing or analogue reference details when producing a construction drawing.
How to read it
- Identify the input supply, reference output and reference return.
- Trace the ADC/DAC reference network and any buffering.
Information to show or reference
- Label the input supply, reference output and reference return.
- Cross-reference the ADC/DAC reference network and any buffering.
- Add the selected device or circuit documentation revision, power/reference connections and project signal convention.
A distinction that matters
A reference establishes a measurement datum; it is not automatically a load-power regulator.
