Product details
Overview
AD9266BCPZ-65 from Analog Devices is a 16-bit, 65 MSPS analog-to-digital converter operating from a single 1.8 V analog supply with 2 Vp-p differential input range, 700 MHz analog input bandwidth, and on-chip voltage reference. It delivers 77.6 dBFS SNR at 9.7 MHz input and 71.1 dBFS at 200 MHz, supporting high-fidelity digitization in software-defined radio receivers.
For engineers reviewing the AD9266BCPZ-65 datasheet, AD9266BCPZ-65 pinout, AD9266BCPZ-65 application, or AD9266BCPZ-65 equivalent, key selection criteria include its 65 MSPS sampling rate, 1.8 V AVDD/DRVDD dual-supply flexibility, interleaved CMOS output interface, programmable clock divider (1-to-8), and industrial temperature range (−40°C to +85°C).
Technical Context
The AD9266BCPZ-65 employs a multistage differential pipeline architecture with error correction logic to guarantee 16-bit accuracy and no missing codes across temperature. Its sample-and-hold circuit supports full performance up to 200 MHz input frequency and integrates a 1.0 V internal reference with ±2 ppm/°C offset drift.
Digital features include SPI-configurable data format (offset binary/Gray/twos complement), optional duty cycle stabilizer, programmable DCO alignment, and built-in deterministic/pseudorandom test pattern generation. Clocking accepts differential CMOS/LVDS/LVPECL inputs with internal 1-to-8 division and 15.38 ns minimum CLK period at 65 MSPS.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit - guarantees monotonicity and no missing codes over full industrial temperature range. |
| Sampling Rate | 65 MSPS - fixed maximum conversion rate for this variant; determines Nyquist bandwidth of 32.5 MHz. |
| SNR @ 9.7 MHz | 77.6 dBFS - defines dynamic range for narrowband IF sampling in communications receivers. |
| SFDR @ 9.7 MHz | 93 dBc - indicates spurious-free resolution for detecting weak signals adjacent to strong interferers. |
| Analog Input BW | 700 MHz - enables direct RF sampling of UHF bands without external anti-alias filtering. |
| Power @ 65 MSPS | 107 mW (DRVDD = 1.8 V) - low power enables battery-powered portable instrumentation. |
| Differential Nonlinearity | −0.6/+1.1 LSB (25°C) - ensures accurate amplitude fidelity in medical ultrasound beamforming. |
Pinout & Package
The AD9266BCPZ-65 is housed in a 32-lead, 5 mm × 5 mm RoHS-compliant LFCSP package with exposed paddle (EPAD) requiring soldering to AGND for thermal, electrical, and mechanical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK+, CLK− | Differential clock input | Accepts CMOS/LVDS/LVPECL; internal common-mode bias at 0.9 V enables robust clock jitter immunity. |
| VIN+, VIN− | Differential analog input | 700 MHz bandwidth, 2 Vp-p full-scale range, 6.5 pF input capacitance for matched transformer coupling. |
| D1_D0 to D15_D14 | Interleaved digital outputs | 16-bit parallel CMOS outputs; reduced pin count via bit-pair interleaving (D1_D0, D3_D2, ..., D15_D14). |
| DCO | Data clock output | Programmable edge-aligned clock for synchronous latching by FPGA/ASIC; supports 1.8 V or 3.3 V logic levels. |
| AVDD (Pins 3,24,29,32) | Analog core supply | Four dedicated 1.8 V pins minimize IR drop and noise coupling into sensitive analog front-end. |
| DRVDD (Pin 13) | Digital output driver supply | 1.8 V to 3.3 V configurable; decouples I/O noise from analog domain and enables mixed-voltage system interfacing. |
| EPAD | Exposed paddle ground | Only ground connection; must be soldered to AGND plane to ensure thermal dissipation (θJA = 37.1°C/W) and noise performance. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip voltage reference | 1.0 V ±1.5% output with 2 mV load regulation error enables stable full-scale calibration without external components. |
| Programmable clock divider | Integer 1-to-8 ratio allows flexible master clock sourcing (e.g., 520 MHz input → 65 MSPS output), reducing clock distribution complexity. |
| Interleaved data output | Bit-pair interleaving (D1_D0, D3_D2, etc.) reduces required PCB routing layers and mitigates simultaneous switching noise in high-speed interfaces. |
| Duty cycle stabilizer (DCS) | Compensates for >40% clock duty cycle variation while maintaining ≤0.1 ps rms aperture jitter-critical for wideband sampling fidelity. |
| Digital test pattern generation | Built-in deterministic, pseudorandom, and user-defined patterns simplify production testing and system-level validation without external signal sources. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9265BCPZ-65 | 16-bit, 65 MSPS, but lacks on-chip voltage reference and requires external 1.0 V reference; identical pinout and timing. | Suitable where board space permits external reference and tighter reference drift (<1 ppm/°C) is needed. | Select AD9265BCPZ-65 only if external reference improves system-level SNR beyond 77.6 dBFS at cost of added BOM and layout complexity. |
| AD9653BCPZ-125 | 16-bit, 125 MSPS, higher power (195 mW), wider analog bandwidth (1.1 GHz), and different pinout (no pin compatibility). | Required for systems needing >65 MSPS sampling, e.g., direct RF sampling above 60 MHz IF. | Choose AD9653BCPZ-125 only when Nyquist bandwidth exceeds 32.5 MHz; not a drop-in replacement due to incompatible footprint and supply sequencing. |
Compared with AD9265BCPZ-65, AD9266BCPZ-65 offers integrated reference convenience at slight SNR trade-off; compared with AD9653BCPZ-125, it provides lower power and proven stability in 65 MSPS IF receiver designs without requiring layout redesign.

FAQ
What is the maximum analog input frequency supported by the AD9266BCPZ-65?
The AD9266BCPZ-65 maintains specified AC performance up to 200 MHz input frequency, with 71.1 dBFS SNR and 80 dBc SFDR measured at that frequency. Its 700 MHz analog input bandwidth ensures minimal amplitude roll-off and phase distortion well beyond the Nyquist limit of 32.5 MHz, enabling undersampling applications in IF and RF receiver chains.
Does the AD9266BCPZ-65 require an external voltage reference?
No, the AD9266BCPZ-65 includes an on-chip 1.0 V voltage reference with ±1.5% initial accuracy and ±2 ppm/°C temperature drift. It can operate in internal reference mode (VREF pin left open or tied to SENSE) or accept an external 1.0 V source for improved stability, but external reference is not required for standard operation of AD9266BCPZ-65.
What digital output formats does the AD9266BCPZ-65 support?
The AD9266BCPZ-65 supports three programmable output data formats via SPI register control: offset binary (default), Gray code, and twos complement. Format selection affects MSB polarity and transition behavior-Gray code minimizes bit errors during code transitions, while offset binary simplifies interface with DSP processors expecting unsigned integer representation.
How is power managed in the AD9266BCPZ-65 during idle periods?
The AD9266BCPZ-65 provides two low-power states: standby mode (44 mW) and full power-down mode (0.5 mW). Standby retains register settings and reference bias; power-down disables all internal circuits except wake-up logic. Both modes are controlled via SPI register 0x08 or static PDWN pin assertion, enabling rapid resumption (350 μs wake-up time) in battery-sensitive applications like handheld scopes.
Is the AD9266BCPZ-65 pin-compatible with other members of the AD9xxx ADC family?
Yes, the AD9266BCPZ-65 uses a 32-lead LFCSP package pin-compatible with AD9609 (10-bit), AD9629 (12-bit), and AD9649 (14-bit) ADCs. This enables hardware reuse across resolution tiers-from 10-bit to 16-bit-within the same 20–80 MSPS sampling range, simplifying migration paths in multi-generation product development.
