How do I start selecting an ADI ADC?

Fix the signal bandwidth and the required accuracy, choose the architecture from the sample rate, then confirm the resolution, the channel count and the interface. Those decisions narrow the selection quickly.

Which ADC architecture should I choose?

Choose a successive-approximation or a sigma-delta part for a low-power or a high-resolution instrument, a simultaneous-sampling part such as the AD7606 for several coherent channels and a pipelined part such as the AD9226 for a single fast channel. Our FAE team can help match the architecture.

How much resolution do I need?

Set the resolution from the smallest signal you must resolve against the noise, not from a wish for the most bits. Add margin for the amplifier noise and the reference drift, and remember that a higher resolution needs a quieter front end to be useful. Read the signal chain design notes for the details.

Are the converters genuine and documented?

Every ADI converter BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file. Mainstream models are held in regional warehouses. Click a model for stock status, or request a quote for current lead time.

How do I start selecting an ADI amplifier?

Describe the source, the required accuracy and the load, choose the topology from the source, then confirm the offset, the noise, the bandwidth and the supply. Those decisions narrow the selection quickly.

Instrumentation or operational amplifier?

Choose an instrumentation amplifier such as the AD620 or the AD8221 for a differential source that needs a high common-mode rejection and a single-resistor gain, and a zero-drift operational amplifier such as the ADA4522-2 for a precision DC path built around a feedback network. Our FAE team can help choose the topology.

How do I read the offset and the noise?

Compare the input offset voltage, the offset drift over temperature and the input voltage and current noise. A low-frequency measurement is limited by the offset drift, while a wideband measurement is limited by the noise, so the priority follows the signal. Read the signal chain design notes for the details.

Are the amplifiers genuine and documented?

Every ADI amplifier BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file. Mainstream models are held in regional warehouses. Click a model for stock status, or request a quote for current lead time.

Why build a power tree from the loads?

Every rail has its own requirement, so start from the loads and the noise target rather than from a favorite part. That gives a tree that meets the efficiency, the noise and the sequencing the system needs. Read the notes for the design rules.

When do I add a low-noise LDO?

Add a low-noise LDO behind a switcher whenever the load is sensitive, such as a converter, a reference or a precision amplifier, because the switcher leaves a ripple that the LDO removes. Place the LDO close to the load. Our FAE team can review the power tree.

How do I keep the emissions low?

Keep the switching loop small, interleave the channels of a multichannel regulator to spread the noise and place the input and output capacitors close to the pins. A well-laid-out switcher meets the emission limit without an external filter in many designs. Our FAE team can review the power layout.

Are the regulators genuine and documented?

Every ADI regulator BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file. Mainstream models are held in regional warehouses. Click a model for stock status, or request a quote for current lead time.

Why budget the noise across the chain?

Every stage adds noise, so the total input-referred noise decides the smallest signal you can resolve. Budget the noise stage by stage, keep the first stage quiet and set the gain so the later stages contribute little. Read the notes for the rules.

How do I ground an analog front end?

Return the analog and the digital currents separately to a single point, keep the digital switching away from the analog inputs and use a ground plane that does not carry the switching current through the sensitive area. The goal is a return path that does not share the analog signal current. Our FAE team can review the grounding.

How do I keep the drive clean?

Drive the converter from a low-distortion amplifier through a small network, keep the source impedance balanced and place the network close to the converter pins. The dynamic performance depends on the drive and the clock quality as much as on the converter. Read the ADC selection guide for the details.

Are the parts genuine and documented?

Every ADI part BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file. Mainstream models are held in regional warehouses. Click a model for stock status, or request a quote for current lead time.

What is the standout feature of the ADI range?

The standout feature is the breadth and the coherence of the signal chain: a converter, an amplifier and a regulator that are specified to work together, with a documentation depth that makes the design predictable. The main care points are the reference and the layout. The review covers the trade-offs.

How do the converters and amplifiers perform?

On the bench the AD7606 held its accuracy across eight coherent channels, the AD8221 and the ADA4522-2 kept a low offset and drift and the AD9226 delivered a clean spectrum at 65 MSPS. The reference and the layout dominated the residual error. Confirm the reference and the drive for your design.

How do the power devices perform?

The ADP5054 delivered four rails with an interleaved switching that kept the input ripple low, and the ADP7118 removed the residual ripple for the analog load. The efficiency matched the datasheet at the working point. Our FAE team can review the power tree.

Can I get samples to evaluate?

Yes. We provide samples of the ADI converters, amplifiers and regulators for your own noise, accuracy and thermal testing, with documentation included and FAE support during bring-up. Request a sample and we will confirm stock and lead time.
