Product details
Overview
AD9266BCPZ-40 from Analog Devices is a 16-bit, 40 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 supports offset binary/Gray/twos complement output formats in communications and medical imaging systems.
For engineers reviewing the AD9266BCPZ-40 datasheet, AD9266BCPZ-40 pinout, AD9266BCPZ-40 application, or AD9266BCPZ-40 equivalent, key selection criteria include its 40 MSPS sampling rate, 1.8 V analog supply compatibility, interleaved CMOS output interface, programmable clock divider (1-to-8), and industrial temperature range (−40°C to +85°C) operation.
Technical Context
The AD9266BCPZ-40 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 supporting differential clock inputs (CMOS/LVDS/LVPECL) with optional duty cycle stabilizer.
Digital features include serial port interface (SPI) for configuration of data alignment, DCO timing, voltage reference mode, and built-in test pattern generation (deterministic, pseudorandom, user-defined). The interleaved 16-bit output uses DCO-synchronized latching and supports 1.8 V to 3.3 V CMOS logic levels via separate DRVDD supply.
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 |
|---|---|---|---|
| AD9265BCPZ-40 | 16-bit, 40 MSPS, but lacks on-chip voltage reference and requires external 1.0 V reference | Higher board area and BOM cost due to external reference circuitry; reduced integration | Select AD9266BCPZ-40 when minimizing component count and layout complexity is critical |
| ADS52J90IRGCT | 16-bit, 40 MSPS, JESD204B serial output instead of parallel CMOS; higher power (125 mW) | Requires FPGA with JESD204B receiver; eliminates 16+ data lines but adds link-layer complexity | Select AD9266BCPZ-40 for legacy parallel interface designs or FPGA I/O-constrained platforms |

FAQ
What is the maximum analog input frequency supported by the AD9266BCPZ-40?
The AD9266BCPZ-40 supports analog input frequencies up to 200 MHz while maintaining specified AC performance, enabled by its 700 MHz analog input bandwidth and optimized sample-and-hold circuit. This allows direct digitization of IF signals in wireless receivers without intermediate downconversion stages.
Does the AD9266BCPZ-40 require an external voltage reference?
No, the AD9266BCPZ-40 includes an on-chip 1.0 V voltage reference with ±12 mV tolerance over temperature. It can operate in internal reference mode using VREF and SENSE pins, eliminating the need for external reference components unless higher precision is required.
What digital output formats does the AD9266BCPZ-40 support?
The AD9266BCPZ-40 supports three configurable digital output formats via SPI register control: offset binary, Gray code, and twos complement. Format selection is performed dynamically without hardware changes, allowing runtime adaptation to host processor requirements.
How is clock duty cycle variation handled in the AD9266BCPZ-40?
The AD9266BCPZ-40 includes an optional duty cycle stabilizer (DCS) that compensates for wide variations in input clock duty cycle while preserving ADC performance. When enabled, DCS ensures consistent aperture timing regardless of input clock asymmetry, critical for high-SNR operation.
What is the power consumption of the AD9266BCPZ-40 at 40 MSPS?
At 40 MSPS with DC input, the AD9266BCPZ-40 consumes 73 mW total (57 mW AVDD + 16 mW DRVDD at 1.8 V). With a full-scale sine-wave input, power rises to 79 mW (DRVDD = 1.8 V) or 93 mW (DRVDD = 3.3 V), making it suitable for thermally constrained portable designs.
