Product details
Overview
AD9625BBPZRL-2.6 from Analog Devices is a 12-bit, 2.6 GSPS analog-to-digital converter optimized for direct RF sampling in spectrum analyzers, radar, and electronic warfare systems. It features 3.2 GHz analog input bandwidth, JESD204B 6- or 8-lane serial output at 6.5 Gbps, dual decimation filters with 10-bit NCOs, and operates from 1.3 V/2.5 V supplies.
For engineers reviewing the AD9625BBPZRL-2.6 datasheet, AD9625BBPZRL-2.6 pinout, AD9625BBPZRL-2.6 application, or AD9625BBPZRL-2.6 equivalent, key selection criteria include SFDR at 1.8 GHz (77 dBc), SNR (57.5 dBFS), noise spectral density (−150.0 dBFS/Hz), and SYSREF±-enabled multichip synchronization for coherent wideband acquisition.
Technical Context
The AD9625BBPZRL-2.6 implements a high-speed pipeline ADC architecture with integrated digital downconverters (DDCs) supporting decimate-by-8 or decimate-by-16 modes. Its differential clock and analog inputs support wideband signal capture up to second Nyquist zone, while the JESD204B Subclass 1 interface ensures deterministic latency and lane alignment via SYSREF±.
It integrates two independent 10-bit numerically controlled oscillators (NCOs), on-chip 1.2 V reference, fast detect output with 82-cycle latency, and timestamping capability. The device supports dc-coupled analog inputs (1.2 V p-p), operates over −40°C to +85°C case temperature, and delivers conversion error rate < 10⁻¹⁵.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9680BCPZ-500 | 14-bit, 500 MSPS; lower speed but higher resolution and SNR (70.2 dBFS); JESD204B subclass 1. | Better suited for high-dynamic-range narrowband applications (e.g., communications test equipment), not wideband RF sampling. | Select when ENOB > 11 bits is required and 2.6 GSPS is unnecessary. |
| ADS54J60IRGCT | 16-bit, 900 MSPS; lower sampling rate, higher power (4.5 W); JESD204B subclass 0; no on-chip DDC or NCO. | Lacks integrated decimation and frequency translation; requires external FPGA logic for IF processing. | Choose for ultra-high-resolution baseband digitization where deterministic latency is less critical than DC accuracy. |
Compared with AD9625BBPZRL-2.6, AD9680BCPZ-500 trades speed for resolution and dynamic range, while ADS54J60IRGCT offers higher ENOB at lower sample rates but omits on-chip DDC functionality-making AD9625BBPZRL-2.6 uniquely balanced for wideband, real-time RF signal intelligence systems.

Does AD9625BBPZRL-2.6 support JESD204B subclass 1 operation?
Yes, AD9625BBPZRL-2.6 fully supports JESD204B subclass 1, including deterministic latency, SYSREF±-based lane alignment, and initial lane alignment sequence (ILAS). This is confirmed in the Functional Block Diagram (Figure 1), Theory of Operation section (page 33), and JESD204B Application Layers (page 48) of the Rev. C datasheet.
What power supply voltages does AD9625BBPZRL-2.6 require?
AD9625BBPZRL-2.6 requires three distinct supply domains: AVDD1/DRVDD1/DVDD1 = 1.3 V (±30 mV), AVDD2/DRVDD2/DVDD2 = 2.5 V (±100 mV), and DVDDIO/SPI_VDDIO = 2.5 V or 3.3 V. These are explicitly defined in Table 1 (DC Specifications) and Absolute Maximum Ratings (Table 6) of the Rev. C datasheet.
Can AD9625BBPZRL-2.6 perform digital downconversion internally?
Yes, AD9625BBPZRL-2.6 integrates two independent digital downconverters (DDCs), each configurable for decimate-by-8 or decimate-by-16 with a 10-bit numerically controlled oscillator (NCO). This capability is detailed in the General Description (page 1), Product Highlights (page 1), and Digital Downconverters section (pages 33–36) of the Rev. C datasheet.
What is the guaranteed conversion error rate for AD9625BBPZRL-2.6?
The AD9625BBPZRL-2.6 guarantees a conversion error rate of less than 10⁻¹⁵, as stated in the FEATURES section (page 1) and confirmed in the AC Specifications table footnote on page 5 of the Rev. C datasheet. This metric reflects bit-error performance under specified operating conditions.
