ADS5560IRGZ25

Analog To Digital Converters (ADC) Overview

The ADS5560IRGZ25 is a single-channel, 16-bit analog-to-digital converter (ADC) from the Texas Instruments ADS556x family. It operates at a maximum sampling rate of 40 MSPS and utilizes a pipeline architecture. The device accepts differential analog inputs and provides digital outputs via Double Data Rate (DDR) LVDS or parallel CMOS interfaces. It functions on 3.3-V analog (AVDD) and digital (DRVDD) supplies. Key performance metrics include an SNR of 84.3 dBFS at a 3 MHz input frequency and an SFDR of 90 dBc under the same conditions. The component is housed in a 48-pin VQFN package with dimensions of 7.00 mm × 7.00 mm.

Analog To Digital Converters (ADC) Feature Summary

• Supports DDR LVDS and parallel CMOS output interface options for flexible system integration.
• Includes a low-frequency noise suppression mode to improve noise performance from DC to approximately 1 MHz.
• Features programmable fine gain adjustment in 1-dB steps up to a maximum of 6 dB.
• Offers internal reference support that eliminates the need for external decoupling capacitors.

Analog To Digital Converters (ADC) Applications

• Medical imaging systems, including MRI applications
• Wireless communications infrastructure
• Software-defined radio platforms
• Test and measurement instrumentation
• High-definition video processing

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current orderable addendum to confirm package type and temperature range. Ensure the selected variant matches the required industrial operating specifications. Cross-reference the datasheet revision history for any updates to electrical characteristics or pin configurations before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and 40 MSPS sampling rate are sufficient for the application. Consider the ADS5562 if an 80 MSPS sampling rate is required, as it shares the same package and pinout. Evaluate the power consumption requirements, noting that total power varies significantly between LVDS and CMOS modes and depends on the selected sample rate.

Analog To Digital Converters (ADC) Part Context

The ADS5560IRGZ25 belongs to the ADS556x family of high-performance ADCs manufactured by Texas Instruments. This family includes the ADS5560 (40 MSPS) and ADS5562 (80 MSPS). Both devices share identical pinouts and packaging, facilitating pin-for-pin compatibility within the series. They are designed to provide high signal integrity for demanding data acquisition tasks.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS5562 serves as a higher-speed alternative within the same family, offering 80 MSPS operation while maintaining the same 48-pin VQFN footprint and pin configuration. Designers requiring increased throughput can substitute the ADS5560 with the ADS5562 without modifying the PCB layout.

Analog To Digital Converters (ADC) FAQ

How does the device handle low-frequency noise?

The ADS5560 includes a dedicated low-frequency noise suppression mode that improves noise performance from DC up to approximately 1 MHz.

What output interface options are available?

The device supports both Double Data-Rate (DDR) LVDS and parallel CMOS output interfaces, which can be selected via the DFS pin.

Is an external reference voltage required?

No, the device features an internal reference that does not require external decoupling capacitors. However, it also supports an external reference mode where the VCM pin acts as the reference input.
