AD9625BBPZRL-2.0

Analog To Digital Converters (ADC) Overview

The AD9625BBPZRL-2.0 is a 12-bit monolithic sampling analog-to-digital converter (ADC) from Analog Devices Inc., operating at conversion rates up to 2.0 GSPS. It features a differential analog input with a 1.1 V p-p range and a 3.2 GHz full-power analog input bandwidth. The device utilizes a high-speed JESD204B serial output interface, configurable in one-, two-, four-, six-, or eight-lane modes, supporting Subclass 1 operation at 5.0 Gbps for the 2.0 GSPS speed grade. Power supplies include 1.3 V and 2.5 V rails. Key performance metrics at 2.0 GSPS include an SFDR of 80 dBc up to 1 GHz input frequency and an SNR of 59 dBFS.

Analog To Digital Converters (ADC) Applications

• Spectrum analyzers
• Military communications systems
• Radar signal processing
• High performance digital storage oscilloscopes

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific speed grade suffix (-2.0) against the required sampling rate specifications. Confirm package type and reel packaging details (RL) match the manufacturing lot requirements. Ensure compatibility with the intended JESD204B link parameters before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 2.0 GSPS maximum sampling rate are required. Consider the 3.2 GHz analog bandwidth for wideband signal acquisition. Evaluate power consumption levels against thermal constraints, as the device dissipates approximately 3.5 W at maximum speed. Verify SPI interface availability for system control.

Analog To Digital Converters (ADC) Part Context

The AD9625 series includes variants optimized for different maximum sampling speeds, specifically 2.0 GSPS, 2.5 GSPS, and 2.6 GSPS. The -2.0 variant is engineered for applications where slightly lower throughput reduces power demands while maintaining high linearity. All variants share the same pinout and functional block diagram, differing primarily in timing specifications and AC performance limits.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements within the AD9625 family include the AD9625-2.5 and AD9625-2.6 for higher speed requirements. For lower speed needs, verify if the AD9625-2.0 meets all AC specifications. Cross-family replacements require careful evaluation of JESD204B compatibility and pin assignments.
