Product details
Overview
AD9626BCPZRL7-210 from Analog Devices is a 12-bit, 210 MSPS analog-to-digital converter optimized for wideband communications and radar subsystems. It delivers 64.2 dBFS SNR at 70 MHz input, 80 dBc SFDR, and 10.5 ENOB with 700 MHz analog bandwidth, operating from a single 1.8 V supply and supporting CMOS output formats.
For engineers reviewing the AD9626BCPZRL7-210 datasheet, AD9626BCPZRL7-210 pinout, AD9626BCPZRL7-210 application, or AD9626BCPZRL7-210 equivalent, key selection criteria include sampling rate scalability (170/210/250 MSPS variants), on-chip reference and track-and-hold integration, programmable input range (1.0–1.5 V p-p), and dual-port interleaved mode support up to 125 MHz.
Technical Context
The AD9626BCPZRL7-210 employs a pipelined switched-capacitor ADC architecture with digital error correction logic and a front-end differential sample-and-hold amplifier. Sampling occurs on the rising clock edge, and each pipeline stage (except the last) includes a low-resolution flash ADC, switched-capacitor DAC, and residue amplifier with 1-bit redundancy.
It supports both single-port CMOS output mode (up to 210 MHz data rate) and interleaved dual-port mode (two 12-bit ports at 105 MHz), with integrated clock duty cycle stabilizer, programmable output coding (offset binary/twos complement/Gray), and serial port interface for configuration of gain, power-down, and test patterns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit - provides 4096 discrete amplitude levels for high-fidelity signal digitization in RF and IF sampling applications. |
| Max Sample Rate | 210 MSPS - enables Nyquist-limited capture of signals up to 105 MHz without aliasing in single-port mode. |
| SNR @ 70 MHz | 64.2 dBFS - ensures >10-bit effective resolution for demanding wideband receiver chains in cable reverse path or radar. |
| Analog BW | 700 MHz - supports direct sampling of L-band and S-band RF signals without external bandpass filtering. |
| Power @ 210 MSPS | 330 mW (single-port) - balances performance and thermal management in dense FPGA-ADC interfaces. |
| Input Range | Programmable 1.0–1.5 V p-p - allows optimization for varying signal chain gain distribution and noise floor trade-offs. |
| Digital Supply | 1.8 V DRVDD - simplifies power delivery by eliminating separate 3.3 V or 2.5 V digital rails required by legacy ADCs. |
Pinout & Package
The AD9626BCPZRL7-210 is housed in a 56-lead LFCSP (CP-56-2) package with exposed paddle soldered to AGND. Pin count and layout are identical across the AD9626 family (170/210/250 MSPS variants).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN+, VIN− | Differential analog input | Accepts ac- or dc-coupled differential signals; internally biased to ~1.4 V common-mode; requires matched source impedance for optimal SFDR. |
| CLK+, CLK− | Differential clock input | Supports CMOS/LVDS/LVPECL; minimum pulse width 2.15 ns; aperture jitter 0.2 ps rms enables clean undersampling of high-frequency carriers. |
| DA0–DA11, DB0–DB11 | CMOS digital output ports | Port A (DAx) and Port B (DBx) deliver 12-bit parallel data; interleaved mode splits conversion results across two ports at half-rate for lower timing margin pressure. |
| DCO+, DCO− | Data clock output | LVDS-compatible output clock synchronized to data edges; used for timing capture in FPGA logic with minimal skew (≤0.55 ns). |
| RBIAS | Chip bias current set | 1% 10 kΩ resistor to ground sets internal bias; critical for maintaining specified linearity (DNL ±0.6 LSB) and SNR over temperature. |
| AVDD, DRVDD | Analog/digital supplies | Separate 1.8 V rails decouple analog core noise from digital switching; AVDD powers SHA and ADC core; DRVDD powers output buffers only. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip reference & T/H | Eliminates need for external voltage reference ICs and discrete track-and-hold circuits-reducing BOM count and board area in compact RF front ends. |
| Programmable output format | Runtime-selectable offset binary, twos complement, or Gray code via SPI-enables seamless integration with Xilinx or Intel FPGA IP cores without external logic translation. |
| Interleaved dual-port mode | Delivers full 12-bit data at 105 MSPS per port-relaxes FPGA I/O timing closure requirements while preserving aggregate throughput and spectral purity. |
| Serial port control (SPI) | Configures gain, power-down, test patterns, and clock duty cycle stabilization-enables dynamic adaptation to changing signal conditions in real-time systems. |
| Single 1.8 V supply operation | Reduces system-level power conversion complexity versus multi-rail ADCs-lowers cost and improves efficiency in battery-powered or thermally constrained designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9625BCPZRL7-250 | 250 MSPS variant with identical pinout, package, and feature set; consumes 364 mW vs. 330 mW at full rate. | Required where Nyquist zone extends beyond 105 MHz (e.g., direct RF sampling at 200+ MHz IF). | Select AD9625BCPZRL7-250 only if system demands >210 MSPS sustained sampling; otherwise AD9626BCPZRL7-210 offers better power/performance trade-off. |
| ADS42JB69IRGCT | Texas Instruments 16-bit, 250 MSPS ADC; higher resolution but larger 64-pin VQFN package and 3.3 V/1.8 V dual supply. | Suitable for applications prioritizing ENOB >12 bits over power or board space constraints. | Choose ADS42JB69IRGCT when quantization noise dominates system error budget; avoid if 1.8 V-only supply or LFCSP footprint is mandatory. |

FAQ
What is the maximum analog input frequency supported by the AD9626BCPZRL7-210?
The AD9626BCPZRL7-210 features a 700 MHz full-power analog bandwidth, enabling direct sampling of signals up to 700 MHz at −3 dB point. For high-fidelity digitization, the device maintains 64.2 dBFS SNR and 80 dBc SFDR at 70 MHz input frequency, making it suitable for L-band and S-band IF sampling in radar and communications systems.
Does the AD9626BCPZRL7-210 require external reference or track-and-hold circuitry?
No, the AD9626BCPZRL7-210 integrates a precision on-chip voltage reference and differential track-and-hold amplifier. This eliminates the need for external reference ICs or discrete T/H components, reducing system complexity, board area, and calibration effort while ensuring consistent performance across temperature and process variations.
How does the interleaved dual-port mode function in the AD9626BCPZRL7-210?
In interleaved dual-port mode, the AD9626BCPZRL7-210 outputs alternating 12-bit samples across two independent CMOS ports (Port A and Port B) at half the sample rate-i.e., 105 MSPS per port. This reduces timing margin pressure on FPGA I/O banks while preserving full 210 MSPS aggregate throughput and maintaining 6-cycle latency.
What power supply requirements does the AD9626BCPZRL7-210 have?
The AD9626BCPZRL7-210 operates from two 1.8 V supplies: AVDD for the analog core (178 mA typical at 210 MSPS) and DRVDD for digital outputs (24 mA typical). Both rails must be well-decoupled; the exposed paddle must be soldered to AGND for thermal and electrical integrity per the LFCSP package specification.
Is the AD9626BCPZRL7-210 pin-compatible with other members of the AD9626 family?
Yes, the AD9626BCPZRL7-210 is fully pin-compatible with the AD9626-170 and AD9626-250 variants. All share identical 56-lead LFCSP packaging, pin assignments, and register map-allowing drop-in replacement across sample rate grades without PCB redesign or firmware changes.
