An isolated ADC converts an analogue measurement into digital information across its specified isolation arrangement.

## In plain English

### What does Isolated analogue-to-digital converter mean?

An isolated ADC converts an analogue measurement into digital information across its specified isolation arrangement.

### A simple example

A converter can provide current or voltage measurement data from one circuit domain to another.

### What the drawings help you do

Identify the analogue measurement domain, isolation boundary and digital output format. Some measurement converters need external filtering or processing to obtain the final reported value. Keep that processing visible so a raw digital stream is not mistaken for an immediately usable engineering-unit reading.

### Before using this reference

- Name the analogue input quantity and scaling.
- Identify the isolation domains and required supplies.
- Reference the digital format and any downstream filtering.

### Is every digital output already a finished voltage or current reading?

No. The selected converter may produce samples or a data stream requiring additional processing. Scaling, filtering and interpretation must follow the actual measurement-chain documentation.

### Terms

- ADC: Analogue-to-digital converter.
- Scaling: The relationship used to turn a converter value into the measured engineering quantity.

## How to read it

- Name the analogue input quantity and scaling.
- Identify the isolation domains and required supplies.
- Reference the digital format and any downstream filtering.
- Conversion, isolation and any required digital filtering are separate parts of the measurement chain.

## Information to show or reference

- Name the analogue input quantity and scaling.
