Product details
Overview
AD9286BCPZ-500 from Analog Devices is an 8-bit, 500 MSPS dual-channel interleaved analog-to-digital converter (ADC) optimized for low-power, high-speed digitization in portable test equipment. It operates from a single 1.8 V supply, delivers 49.3 dBFS SNR at 200 MHz input, 65 dBc SFDR, and features LVDS digital outputs with on-chip reference and track-and-hold. It targets handheld oscilloscopes and battery-powered instrumentation requiring compact, thermally efficient sampling.
For engineers reviewing the AD9286BCPZ-500 datasheet, AD9286BCPZ-500 pinout, AD9286BCPZ-500 application, or AD9286BCPZ-500 equivalent, key selection considerations include its 500 MSPS effective sample rate via internal clock interleaving, 1.2 Vp-p differential analog input range, −40°C to +85°C industrial temperature rating, and 48-lead LFCSP package with exposed thermal pad grounding requirement.
Technical Context
The AD9286BCPZ-500 implements a two-channel time-interleaved pipeline ADC architecture, where each core runs at 250 MSPS and is synchronized by an on-chip clock divider to achieve 500 MSPS aggregate throughput. Sampling edge timing per channel is adjustable via SPI to minimize image spurs.
It integrates differential input buffers with 500 MHz bandwidth, on-chip 1.0 V reference, track-and-hold, and LVDS output drivers powered by a dedicated 1.8 V DRVDD rail. Digital interface includes SPI-configurable options for data format (offset binary/Gray/twos complement), clock duty cycle stabilization, and built-in test pattern generation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8-bit - defines quantization granularity and dynamic range ceiling for baseband signal capture. |
| Sample Rate | 500 MSPS effective - achieved via precise time interleaving of two 250 MSPS ADC cores; enables Nyquist zone up to 250 MHz. |
| SNR @ 200 MHz | 49.3 dBFS - determines minimum detectable signal level above noise floor in wideband applications. |
| SFDR @ 200 MHz | 65 dBc - specifies largest spur amplitude relative to full-scale fundamental, critical for multi-tone signal integrity. |
| Power Consumption | 315 mW at 500 MSPS - enables thermal management in space-constrained handheld instruments without active cooling. |
| Analog Input Range | 1.2 Vp-p differential - sets required driver output swing and defines headroom for anti-alias filtering design. |
| Digital Interface | LVDS outputs - provides noise-immune, low-skew data transmission compatible with FPGA/CPLD receivers at 500 MSPS. |
Pinout & Package
AD9286BCPZ-500 is housed in a Pb-free, 48-lead LFCSP (CP-48-14) package with exposed thermal pad (AGND) that must be soldered to PCB analog ground for functionality, thermal dissipation, and noise control.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN1+, VIN1− VIN2+, VIN2− | Differential analog inputs (Ch1 & Ch2) | Accept 1.2 Vp-p differential signals with 500 MHz bandwidth; require matched trace lengths and impedances to minimize inter-channel mismatch distortion. |
| CLK+, CLK− AUXCLK+, AUXCLK− | Differential clock inputs | Support LVDS/LVPECL/sine wave clocks; AUXCLKEN pin selects auxiliary clock usage for simultaneous sampling mode. |
| D7+ to D0+, D7− to D0− | LVDS digital outputs (8-bit data) | Deliver offset binary (default), Gray, or twos complement data; MSB/LSB polarity marked; require 100 Ω differential termination. |
| DCO+, DCO− | Data clock output | Provides source-synchronous LVDS clock aligned to data edges; used for timing capture in FPGA-based receivers. |
| SDIO/PWDN, CSB, SCLK | SPI serial interface | Enable register configuration (timing adjustment, test modes, power-down); PWDN function available in external mode only. |
| OE | Output enable (active low) | Tri-states all LVDS data and DCO outputs; supports shared bus architectures and low-power idle states. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip interleaved clocking | Eliminates need for external clock multiplexers or phase alignment circuitry; reduces board-level jitter sensitivity and layout complexity. |
| Pin-programmable power-down | Reduces power to ≤1.7 mW; enables rapid wake-up (<500 μs) for burst-mode acquisition in portable instruments. |
| Built-in digital test pattern generation | Supports production testing and system-level validation without external pattern generators; selectable via SPI or pins. |
| Interleaved clock timing adjustment | Allows fine-tuning of sampling edge per ADC core via SPI to suppress interleave spurs below −70 dBc. |
| Differential input with 500 MHz bandwidth | Enables direct RF sampling in first Nyquist zone up to 250 MHz; eliminates need for IF downconversion stages. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9283BCPZ-250 | Single-channel, 250 MSPS, 8-bit, same 1.8 V supply and LVDS outputs; no interleaving or AUXCLK support. | Lower sample rate limits Nyquist zone to 125 MHz; suitable for cost-sensitive single-channel systems without interleaving artifacts. | Select when 250 MSPS suffices and board space/power budget precludes dual-core complexity. |
| ADS52J90IRGCT | Texas Instruments 10-bit, 250 MSPS dual-channel ADC; higher resolution but lower speed; JESD204B serial interface instead of parallel LVDS. | Requires FPGA with JESD204B PHY; better ENOB (8.2 bits) but lower SFDR (62 dBc at 200 MHz) and higher power (540 mW). | Select when resolution >8 bits is mandatory and system already uses JESD204B infrastructure. |
Compared with AD9286BCPZ-500, AD9283BCPZ-250 trades half the sample rate and single-channel operation for reduced layout sensitivity and lower cost, while ADS52J90IRGCT offers higher resolution and serial interface at the expense of speed, power, and interface compatibility.

FAQ
What is the maximum analog input frequency supported by the AD9286BCPZ-500?
The AD9286BCPZ-500 has a full-power analog input bandwidth of 700 MHz and is characterized for AC performance up to 220 MHz input with 49.3 dBFS SNR. Its 500 MSPS sample rate supports Nyquist zones up to 250 MHz, making it suitable for undersampling applications in the first or second Nyquist zone. Performance beyond 220 MHz depends on system-level layout, clock jitter, and input drive strength.
Does the AD9286BCPZ-500 require external reference components?
No, the AD9286BCPZ-500 includes an on-chip 1.0 V voltage reference and track-and-hold circuit, eliminating the need for external reference ICs in most applications. An external reference can be applied via the VREF pin if tighter accuracy or temperature stability is required. A 10 kΩ resistor must be connected from RBIAS to AGND to set the master current reference.
How is the 500 MSPS sample rate achieved in the AD9286BCPZ-500?
The AD9286BCPZ-500 achieves 500 MSPS through internal time interleaving of two independent 250 MSPS ADC cores. A single input clock is divided on-chip, and each core samples alternately. Interleaving timing is adjustable via SPI to minimize spurious energy from channel mismatch, enabling clean wideband performance without external clock synthesis.
What are the power supply requirements for the AD9286BCPZ-500?
The AD9286BCPZ-500 requires two 1.8 V supplies: AVDD (125–130 mA) for analog circuitry and DRVDD (51–54 mA) for LVDS output drivers. Both rails must be independently decoupled. Absolute maximum ratings allow 1.7 V to 1.9 V; operation outside this range may cause parametric degradation or damage. The exposed thermal pad (AGND) must be soldered to PCB analog ground.
Can the AD9286BCPZ-500 operate in single-channel mode?
Yes, the AD9286BCPZ-500 supports both interleaved (default, 500 MSPS) and simultaneous sampling modes via the AUXCLKEN pin. In simultaneous mode, both channels sample at 250 MSPS on the same clock edge, delivering true dual-channel capture with matched timing-ideal for I/Q demodulation or differential signal analysis without interleaving artifacts.
