Data converters
Source your approved ADC or DAC with the ordering details intact. We review converter requirements against the exact part, packaging, quantity and agreed inspection scope.
Start with your approved part numbers
ADC and DAC requirements solve different jobs in a signal chain. Resolution alone is not a purchasing substitute: interface, output type, channel configuration, reference requirements and package can all matter to an approved design.
For example, Analog Devices describes AD420 as a 16-bit current-output DAC. Its ordering table lists AD420ARZ-32 and AD420ARZ-32-REEL separately. Keep the requested ordering model intact instead of reducing it to “AD420”.
Ordering details that matter
Keep device identity and offered-lot details separate.
The most useful RFQ starts with an approved full manufacturer part number, then adds your commercial and acceptance requirements. Use the checks below to make those requirements clear.
| Check | Why it matters | What to send |
|---|---|---|
| ADC or DAC identity | Equal resolution does not mean equal function. | Give the exact ordering code and approved manufacturer. |
| Package and ordering model | Carrier suffixes are part of the requested order configuration. | Preserve suffixes such as -REEL and state whether other carriers are acceptable. |
| Acceptance parameters | Output accuracy, dynamic behavior and interface operation are different tests. | Specify the parameters, limits and operating conditions you need checked. |
| Lot and delivery | Device specifications do not establish present stock or its packaging. | Add quantity, required date and any lot/date-code restrictions. |
Lot evidence and inspection
Define what needs to be verified before the order.
Electrical testing of a converter needs an agreed setup, reference conditions and pass/fail limits. A report that shows package appearance or marking consistency does not establish conversion accuracy, noise performance or dynamic specifications.
We can coordinate the selected independent laboratory scope for the offered lot, with the sample quantity and untested characteristics made explicit.

Find the right product information
Browse related procurement guidance or send an unlisted requirement.
Use these related pages to narrow the device identity and the evidence needed for your order. If your exact part is not listed, send the complete MPN and quantity. We review available stock and additional supply options against your requirements.
Pricing, lot details and delivery are confirmed in the quotation. For multiple parts, send your BOM with one ordering code per line.
Before you enquire
Is another 16-bit DAC an acceptable replacement?
Not on that description alone. Your engineering team must approve the exact alternative against the application and manufacturer documentation.
Can output performance be checked before shipment?
Include the parameters, conditions and sample requirements in the RFQ. Test feasibility and the laboratory scope must be agreed before they become part of the order.
