Product details
Overview
AD9625BBP-2.5 from Analog Devices is a 12-bit, 2.5 GSPS analog-to-digital converter optimized for direct RF sampling in wideband systems. It features 3.2 GHz analog input bandwidth, −149.5 dBFS/Hz noise spectral density, differential JESD204B serial output (6- or 8-lane), and dual decimation filters with 10-bit NCOs. It serves as the front-end digitizer in radar receivers and electronic warfare signal analyzers.
For engineers reviewing the AD9625BBP-2.5 datasheet, AD9625BBP-2.5 pinout, AD9625BBP-2.5 application, or AD9625BBP-2.5 equivalent, key selection criteria include SFDR at 1.8 GHz (77 dBc), SNR at 1 GHz (57.6 dBFS), JESD204B Subclass 1 compliance, dual DDC capability, and 1.3 V/2.5 V dual-supply operation.
Technical Context
The AD9625BBP-2.5 implements a high-speed pipeline ADC architecture with on-chip 1.2 V reference and differential clock input. Its analog front end supports full-power input up to 3.2 GHz and accepts 1.2 V p-p differential signals referenced to 525 mV common-mode voltage.
Digital processing includes two independent decimate-by-8 or decimate-by-16 filters, each with a 10-bit numerically controlled oscillator (NCO) for frequency translation, and a timestamp-enabled SYSREF± interface for multichip synchronization in phased-array or MIMO systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9625BBP-2.6 | Higher max sample rate (2.6 GSPS); identical pinout, package, and feature set; slightly higher power (4.3 W vs. 4.2 W). | Same radar/EW use cases but supports marginally wider instantaneous bandwidth (1.3 GHz Nyquist zone). | Select AD9625BBP-2.6 only if system requires >2.5 GSPS sampling; otherwise AD9625BBP-2.5 offers optimal power/performance trade-off. |
| AD9680BCPZ-500 | Lower sample rate (500 MSPS); dual 14-bit channels; no on-chip DDC; JESD204B Subclass 0 only. | Better suited for lower-frequency, higher-resolution applications like medical ultrasound or test equipment where SNR >65 dBFS is prioritized over bandwidth. | Choose AD9680BCPZ-500 when resolution and SNR outweigh raw speed; not suitable for direct RF sampling above 250 MHz. |
Compared with AD9625BBP-2.6, the AD9625BBP-2.5 trades 100 MSPS of maximum rate for reduced power and thermal load while retaining identical DDC, JESD204B, and SYSREF functionality; compared with AD9680BCPZ-500, it delivers 5× higher sample rate and integrated RF-sampling features at the cost of 2-bit resolution and higher system complexity.

FAQ
What is the maximum analog input frequency supported by the AD9625BBP-2.5?
The AD9625BBP-2.5 supports full-power analog input signals up to 3.2 GHz, as specified in its analog input bandwidth parameter. This enables direct sampling of RF carriers in the L-, S-, and lower C-bands without downconversion. Performance metrics such as SFDR and SNR are validated up to 1.8 GHz at −1 dBFS, confirming usable dynamic range across this extended band.
Does the AD9625BBP-2.5 require an external reference voltage?
No, the AD9625BBP-2.5 integrates a precision 1.2 V internal reference and does not require an external reference. The device is fully functional with its on-chip reference enabled, simplifying layout and improving SNR stability. External reference bypassing is optional and only used in specialized calibration scenarios per the datasheet's "Reference" section.
How many JESD204B lanes does the AD9625BBP-2.5 support, and what is the maximum lane rate?
The AD9625BBP-2.5 supports configurable 6- or 8-lane JESD204B Subclass 1 operation. At 2.5 GSPS, the maximum lane rate is 6.25 Gbps (6-lane mode) or 5.21 Gbps (8-lane mode). The interface complies with JESD204B revision B and supports deterministic latency, multi-device synchronization via SYSREF±, and ILAS-based link initialization.
What are the power supply requirements for the AD9625BBP-2.5?
The AD9625BBP-2.5 requires two analog supply domains (AVDD1 = 1.3 V, AVDD2 = 2.5 V), two digital supply domains (DVDD1 = 1.3 V, DVDD2 = 2.5 V), one driver supply (DRVDD1 = 1.3 V, DRVDD2 = 2.5 V), and separate I/O supplies (DVDDIO = 2.5 V, SPI_VDDIO = 2.5 V). Total power dissipation in eight-lane mode is 4.2 W at 2.5 GSPS, with dedicated ground planes (AGND, DGND, DRGND) required per the layout guidelines.
Can the AD9625BBP-2.5 perform frequency translation internally?
Yes, the AD9625BBP-2.5 includes two independent digital downconverters (DDCs), each with a 10-bit numerically controlled oscillator (NCO) and selectable decimation by 8 or 16. This enables real-time, in-ADC frequency translation and channelization-eliminating the need for post-digitization FPGA-based mixing in many wideband receiver designs.
