Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current orderable addendum to ensure correct packaging and tape/reel specifications. Confirm that the component meets RoHS compliance requirements for your region. Check for any recent design changes or product discontinuation notices via official technical documentation channels before finalizing procurement plans.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS5562IRGZ25 when high-resolution 16-bit conversion is required at sampling rates up to 80 MSPS. Choose this part over the ADS5560 if higher bandwidth and faster throughput are necessary. Ensure the design accommodates the 3.3 V supply rails and select between LVDS or CMOS outputs based on downstream logic compatibility and trace length constraints.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS556x family of high-performance ADCs, which also includes the ADS5560 variant operating at 40 MSPS. Both devices share similar pinouts and feature sets, including the 48-pin VQFN package and internal reference capabilities. The ADS5562 serves as the high-speed option within this specific series designed for demanding signal acquisition tasks.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS5560 is a parameter-equivalent alternative within the same family but operates at a lower maximum sample rate of 40 MSPS. Verify that the reduced bandwidth of the ADS5560 meets the specific Nyquist zone requirements of the application before considering it as a substitute.

Analog To Digital Converters (ADC) FAQ

How does the low-frequency noise suppression mode function?

This mode improves noise performance specifically in the frequency range from DC to approximately 1 MHz, enhancing signal integrity for low-frequency inputs.

What is the purpose of the MODE pin?

The MODE pin selects between internal and external reference modes. In external mode, the VCM pin acts as the reference input.

Can the output interface be changed dynamically?

Yes, the DFS pin allows selection between DDR LVDS and parallel CMOS output modes, determining the data format and interface type.
