Product details
Overview
AD9266-40EBZ from Analog Devices is a 16-bit, 40 MSPS analog-to-digital converter (ADC) operating from a single 1.8 V analog supply with differential 700 MHz input bandwidth, 2 Vp-p full-scale input range, and on-chip voltage reference. It delivers 77.9 dBFS SNR at 9.7 MHz input and supports offset binary/Gray/twos complement output formats for communications receiver front-ends.
For engineers reviewing the AD9266-40EBZ datasheet, AD9266-40EBZ pinout, AD9266-40EBZ application, or AD9266-40EBZ equivalent, this evaluation board enables rapid characterization of high-fidelity digitization in diversity radio systems, portable ultrasound, and smart antenna baseband chains under real-world clock jitter and wideband analog input conditions.
Technical Context
The AD9266-40EBZ implements a multistage differential pipeline architecture with output error correction logic to guarantee 16-bit accuracy and no missing codes across −40°C to +85°C. Its sample-and-hold circuit maintains ≤0.1 ps rms aperture jitter up to 200 MHz input frequency.
It features a programmable 1-to-8 internal clock divider, optional duty cycle stabilizer (DCS), and serial port interface (SPI) for configuring data alignment, DCO timing, voltage reference modes, and built-in test patterns-including deterministic, pseudorandom, and user-defined sequences.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit - guarantees monotonicity and no missing codes over full temperature range |
| Sample Rate | 40 MSPS - fixed maximum conversion rate for AD9266-40 variant; supports Nyquist-limited IF sampling up to 20 MHz |
| SNR @ 9.7 MHz | 77.9 dBFS - enables >12.6 ENOB for high-fidelity signal capture in LTE/W-CDMA receivers |
| SFDR @ 9.7 MHz | 95.1 dBc - suppresses spurious content critical for adjacent-channel rejection in multimode digital receivers |
| Analog Input BW | 700 MHz - supports direct RF sampling of L-band signals without external amplification or filtering |
| Power @ 40 MSPS | 73 mW (DC input) - low power enables battery operation in handheld scope meters and portable medical imaging |
| Differential Inputs | VIN+, VIN− - accepts 2 Vp-p differential signal with 0.9 V common-mode voltage; compatible with transformer or balun coupling |
Pinout & Package
The AD9266-40EBZ evaluation board interfaces with the AD9266-40 IC housed in a 32-lead, 5 mm × 5 mm RoHS-compliant LFCSP package with exposed paddle (EPAD) soldered to AGND for thermal and noise integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK+, CLK− | Differential clock input | Accepts CMOS/LVDS/LVPECL; internal bias sets common-mode to 0.9 V; enables jitter-insensitive sampling |
| VIN+, VIN− | Analog input pair | 700 MHz bandwidth; 2 Vp-p full-scale; 6.5 pF input capacitance; requires matched trace routing |
| D1_D0 to D15_D14 | Interleaved CMOS digital outputs | 16-bit parallel data bus; LSB-to-MSB grouping reduces pin count vs. full 16-bit bus; supports 1.8 V/3.3 V logic |
| DCO | Data clock output | Programmable edge-aligned clock for synchronous latching; minimizes setup/hold violations in FPGA interfaces |
| CSB, SCLK/DFS, SDIO/PDWN | SPI control interface | 3-wire serial port for register configuration; DFS pin selects output format in hardware mode without SPI |
| AVDD, DRVDD | Power domains | Separate 1.8 V analog core (AVDD) and 1.8–3.3 V digital output (DRVDD) supplies enable mixed-voltage system integration |
| EPAD | Thermal & ground connection | Only ground path for die; must be soldered to solid AGND plane to ensure thermal dissipation and low-noise performance |
Key Features
| Feature | Design Value |
|---|---|
| On-chip voltage reference | 1.0 V ±12 mV output with 2 mV load regulation error ensures stable full-scale calibration without external components |
| Programmable clock/data alignment | SPI-adjustable DCO phase and data edge timing eliminates manual PCB delay tuning for FPGA-based receivers |
| Interleaved 16-bit output | D1_D0 through D15_D14 grouped as 8 dual-bit terminals reduces I/O count by 50% versus discrete bit lines |
| Built-in test pattern generation | Supports deterministic, pseudorandom, and custom SPI-loaded patterns for production testing without external signal sources |
| Integer 1-to-8 clock divider | Enables use of higher-frequency, lower-jitter master clocks while maintaining precise 40 MSPS sampling rate |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-resolution ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9265-40EBZ | 16-bit, 40 MSPS, but uses 3.3 V AVDD and lacks integrated voltage reference; requires external 1.25 V reference | Better suited for legacy 3.3 V systems with existing reference infrastructure; higher power (125 mW) | Select when migrating from older AD92xx designs with 3.3 V analog rails and external reference tolerance |
| ADS58C20EVM | 11-bit, 200 MSPS dual-channel ADC; no on-chip reference; LVDS outputs only; higher power (420 mW) | Targets wideband spectrum analysis and MIMO radar where speed outweighs resolution | Select when system requires >100 MSPS sampling or dual-channel parallel acquisition, not 16-bit fidelity |
Compared with AD9266-40EBZ, AD9265-40EBZ trades integrated reference and lower voltage for higher power and legacy compatibility, while ADS58C20EVM sacrifices resolution and adds channel count to achieve 5× higher sample rate-making AD9266-40EBZ optimal for resolution-critical, power-constrained IF digitization.

FAQ
What is the primary function of the AD9266-40EBZ evaluation board?
The AD9266-40EBZ evaluation board is designed to demonstrate and characterize the AD9266-40 16-bit, 40 MSPS analog-to-digital converter. It provides standardized connectors, clock conditioning, power regulation, and FPGA-compatible digital interfaces to accelerate development of high-fidelity digitization systems. The board enables full validation of SNR, SFDR, and timing parameters specified in the AD9266-40 datasheet Rev. B.
Does the AD9266-40EBZ support DC-coupled analog inputs?
Yes, the AD9266-40EBZ supports DC-coupled analog inputs via the VIN+ and VIN− pins, which accept a 2 Vp-p differential signal with 0.9 V common-mode voltage. The board includes AC/DC coupling jumpers and matching network options; for DC coupling, users must ensure the input source drives the correct common-mode level and complies with absolute maximum ratings (−0.3 V to AVDD + 0.2 V).
How does the AD9266-40EBZ handle clock jitter sensitivity?
The AD9266-40EBZ leverages the AD9266-40's on-chip duty cycle stabilizer (DCS) and ≤0.1 ps rms aperture jitter to maintain 77.9 dBFS SNR even with asymmetric clock inputs. The evaluation board includes selectable clock input paths (LVDS, CMOS, transformer-coupled) and onboard termination to minimize reflection-induced jitter, ensuring robust performance in noisy RF environments.
Can the AD9266-40EBZ operate with a 3.3 V digital interface?
Yes, the AD9266-40EBZ supports 3.3 V CMOS-level digital outputs via the DRVDD supply pin. When DRVDD is set to 3.3 V, the D1_D0–D15_D14 outputs and DCO meet 3.3 V logic thresholds (VOH ≥ 3.25 V, VOL ≤ 0.2 V at specified loads), enabling direct interfacing with 3.3 V FPGAs or ASICs without level shifters.
Is the AD9266-40EBZ pin-compatible with other AD9266 speed grades?
Yes, the AD9266-40EBZ evaluation board is mechanically and electrically compatible with all AD9266 speed variants (AD9266-20, AD9266-40, AD9266-65, AD9266-80) because they share identical 32-lead LFCSP packaging, pinout, and register map. Firmware and layout can be reused across sample rates, with only clocking and power settings requiring adjustment.
