Lookup label: VREF-S
Drawing use: Schematic
Reference families: Manufacturer

Provides a reference voltage through a series-connected supply and output arrangement.

## 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.

## Important distinction

A reference establishes a measurement datum; it is not automatically a load-power regulator.

## Facts

- Common schematic mnemonic: VREF-S — descriptive only; project/device documentation defines reference designations.
- Terminal / interface focus: The input supply, reference output and reference return
- Artwork scope: Original educational functional/circuit reference; not a selected product pinout.

## Public references

- [ADR4525 — series voltage reference](https://www.analog.com/en/products/adr4525.html) — Analog Devices. Public primary manufacturer documentation establishes the component function or circuit/topology relationship. Preview geometry and drafting explanations are independently authored.
