Lookup label: ISO-AMP
Drawing use: Schematic
Reference families: Manufacturer

Transfers an analogue measurement across the documented electrical isolation boundary.

## What it represents

Transfers an analogue measurement across the documented electrical isolation boundary.
On a schematic, identify the two supply domains, input reference and output interface and trace the isolated measurement signal and downstream processing. Keep the component tag and signal/reference names consistent across the control drawing, terminal schedule and device documentation.
An isolation amplifier has an analogue signal-transfer role; a digital isolator transfers encoded logic rather than a generic continuous voltage.
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 two supply domains, input reference and output interface.
- Trace the isolated measurement signal and downstream processing.

## Information to show or reference

- Label the two supply domains, input reference and output interface.
- Cross-reference the isolated measurement signal and downstream processing.
- Add the selected device or circuit documentation revision, power/reference connections and project signal convention.

## Important distinction

An isolation amplifier has an analogue signal-transfer role; a digital isolator transfers encoded logic rather than a generic continuous voltage.

## Facts

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