Product details
Overview
AD9266TCPZ-65EP from Analog Devices is a 16-bit, 65 MSPS analog-to-digital converter operating from a single 1.8 V analog supply with differential 700 MHz input bandwidth, 2 Vp-p input span, and on-chip voltage reference. It delivers 77.6 dBFS SNR at 9.7 MHz and 71.1 dBFS at 200 MHz input, supporting high-fidelity digitization in ultrasound front-ends and LTE baseband receivers.
For engineers reviewing the AD9266TCPZ-65EP datasheet, AD9266TCPZ-65EP pinout, AD9266TCPZ-65EP application, or AD9266TCPZ-65EP equivalent, key selection considerations include its 32-lead LFCSP package, programmable clock divider (1-to-8), interleaved CMOS output interface, and support for offset binary/Gray/twos complement data formats - all critical for low-power, high-dynamic-range signal acquisition systems.
Technical Context
The AD9266TCPZ-65EP employs 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 performance up to 200 MHz input frequency while consuming only 113 mW at full 65 MSPS operation with DRVDD = 1.8 V.
Digital interface flexibility is enabled by a standard SPI port controlling data formatting, DCO alignment, power-down modes, and internal reference selection. The differential clock input accepts CMOS/LVDS/LVPECL levels, and an optional duty cycle stabilizer mitigates clock asymmetry without degrading AC performance.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-resolution ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9649BCPZ-80 | 14-bit, 80 MSPS, same 32-lead LFCSP package and pinout; lower resolution but higher speed and lower power (98 mW). | Better suited for wideband spectrum monitoring where 14-bit ENOB suffices and latency <10 cycles is critical. | Select AD9649BCPZ-80 when system SNR requirement is ≤72 dBFS and board layout re-use with AD9266 footprint is prioritized. |
| ADS58C28IRGCT | Texas Instruments 11-bit, dual-channel 200 MSPS ADC; 48-pin QFN; requires external reference and separate analog/digital supplies. | Targeted at multi-carrier GSM/EDGE base stations needing simultaneous I/Q sampling at >100 MHz IF. | Choose ADS58C28IRGCT only if dual-channel operation, >100 MSPS aggregate throughput, and external reference flexibility outweigh resolution loss. |
Compared with AD9266TCPZ-65EP, AD9649BCPZ-80 trades 2 bits of resolution for 15 MSPS higher sample rate and 15 mW lower power, while ADS58C28IRGCT offers dual-channel parallelism at significantly lower resolution and higher system-level design complexity.

FAQ
What is the maximum analog input frequency supported by the AD9266TCPZ-65EP?
The AD9266TCPZ-65EP supports analog input frequencies up to 200 MHz while maintaining specified SNR and SFDR performance. Its 700 MHz analog input bandwidth ensures minimal attenuation and phase distortion across this range, making it suitable for undersampling applications in radar and broadband communications where aliasing is managed digitally.
Does the AD9266TCPZ-65EP require an external voltage reference?
No, the AD9266TCPZ-65EP includes an on-chip 1.0 V voltage reference with ±1.5% accuracy and 2 mV load regulation error. External reference is optional and only needed when tighter initial accuracy or temperature drift specifications are required beyond the internal reference's capabilities.
How does the duty cycle stabilizer (DCS) affect the AD9266TCPZ-65EP's AC performance?
The optional duty cycle stabilizer in the AD9266TCPZ-65EP corrects wide variations in input clock duty cycle without degrading SNR or SFDR. At 9.7 MHz input, measured SNR remains 77.6 dBFS and SFDR stays at 93 dBc even with highly asymmetric clocks, preserving dynamic range in systems using non-50% duty cycle clock sources.
What digital output formats does the AD9266TCPZ-65EP support?
The AD9266TCPZ-65EP supports three configurable digital output formats: offset binary, Gray code, and twos complement. Format selection is controlled via SPI register or static pin (DFS) configuration, enabling compatibility with diverse FPGA logic families and simplifying data parsing in real-time signal processing pipelines.
Is the AD9266TCPZ-65EP pin-compatible with other members of the AD9xxx ADC family?
Yes, the AD9266TCPZ-65EP uses a 32-lead LFCSP package pin-compatible with the AD9609 (10-bit), AD9629 (12-bit), and AD9649 (14-bit) ADCs. This enables hardware reuse and migration paths between resolutions and sample rates from 20 MSPS to 80 MSPS without PCB redesign.
