Product details
Overview
AD9287ABCPZ-100 from Analog Devices is a quad-channel, 8-bit, 100 MSPS analog-to-digital converter with serial LVDS output, 1.8 V supply operation, 295 MHz full-power analog bandwidth, and on-chip sample-and-hold-designed for medical ultrasound beamforming and quadrature radio receivers.
For engineers reviewing the AD9287ABCPZ-100 datasheet, AD9287ABCPZ-100 pinout, AD9287ABCPZ-100 application, or AD9287ABCPZ-100 equivalent, key selection criteria include SNR (49 dB), ENOB (7.85 bits), SFDR (65 dBc), serial LVDS compliance (ANSI-644), and 48-lead LFCSP package thermal performance.
Technical Context
The AD9287ABCPZ-100 implements a 3-section pipelined ADC architecture: a 4-bit first stage, eight 1.5-bit interstage sections with MDAC residue amplification, and a final 3-bit flash stage-enabling 100 MSPS conversion with 8 clock-cycle pipeline latency. Each stage uses 1-bit redundancy for digital error correction.
It integrates four independent ADC cores sharing a common 1.8 V AVDD/DRVDD supply, supports programmable clock/data alignment, offers dual LVDS output modes (standard and low-power reduced-signal), and provides frame clock (FCO) and data clock (DCO) outputs synchronized to serialized 8-bit offset-binary data streams.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8-bit - fixed precision suitable for medium-dynamic-range signal acquisition in portable ultrasound and diversity receivers. |
| Sampling Rate | 100 MSPS - enables Nyquist-limited digitization of signals up to 50 MHz without aliasing in baseband applications. |
| SNR | 49 dB (to Nyquist) - delivers usable dynamic range for RF/IF sampling where spurious-free resolution is critical. |
| ENOB | 7.85 bits at 49.7 MHz input - confirms effective linearity and noise floor performance under real-world RF conditions. |
| SFDR | 65 dBc (to Nyquist) - ensures clean spectral representation for multi-tone signals in communication and test equipment. |
| Analog Bandwidth | 295 MHz - supports direct sampling of IF signals up to ~150 MHz with ≤3 dB attenuation. |
| Power per Channel | 133 mW at 100 MSPS - enables compact, thermally constrained designs such as handheld ultrasound probes. |
| Supply Voltage | 1.8 V AVDD/DRVDD - reduces system-level power delivery complexity and EMI compared to 3.3 V or 5 V ADCs. |
Pinout & Package
The AD9287ABCPZ-100 is housed in a RoHS-compliant, 48-lead LFCSP (Lead Frame Chip Scale Package) with exposed paddle requiring connection to AGND for thermal and electrical integrity.

Key Features
| Feature | Design Value |
|---|---|
| Quad ADC integration | Four independent 8-bit 100 MSPS converters in single 48-lead LFCSP - reduces PCB area and inter-channel skew vs. discrete solutions. |
| Serial LVDS output | ANSI-644-compliant differential signaling with programmable low-power mode - minimizes EMI and improves noise immunity over FR-4 traces. |
| Programmable clock/data alignment | SPI-controlled phase adjustment of DCO/FCO relative to data - eliminates external delay tuning for FPGA/CPLD capture timing closure. |
| Built-in test pattern generation | Deterministic, pseudorandom, and custom user-defined patterns via SPI - enables in-system ADC validation without external signal sources. |
| Individual channel power-down | Per-channel disable via SPI register - allows dynamic channel gating in beamforming or diversity systems to reduce real-time power by >95%. |
| Flexible bit orientation | Configurable MSB-first or LSB-first serialization - simplifies interface to heterogeneous digital backends without external bit-reversal logic. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel, 8-bit, 100 MSPS ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9219BCPZ-100 | 10-bit resolution, same 48-lead LFCSP package and pinout; higher SNR (54 dB) but 2× power (260 mW/channel). | Better dynamic range for demanding test equipment; less suitable for ultra-low-power portable ultrasound. | Select when ENOB > 8.2 bits is required and thermal budget allows +130 mW/channel. |
| AD9228BCPZ-100 | 12-bit resolution, identical footprint and interface; 3× power (390 mW/channel), lower SFDR (58 dBc at 100 MSPS). | Targeted at high-fidelity medical imaging (e.g., MRI front-ends); not optimized for RF spectral purity. | Choose for DC-coupled, low-frequency precision applications where resolution outweighs RF linearity and power constraints. |
Compared with AD9287ABCPZ-100, AD9219BCPZ-100 trades 2-bit resolution gain for +130 mW/channel and improved SFDR, while AD9228BCPZ-100 adds 4-bit resolution at significantly higher power and reduced high-frequency linearity-making AD9287ABCPZ-100 optimal for balanced RF performance in space- and power-constrained systems.

FAQ
What is the maximum analog input frequency supported by the AD9287ABCPZ-100?
The AD9287ABCPZ-100 features a 295 MHz full-power analog bandwidth, meaning it maintains ≤3 dB attenuation up to 295 MHz. This supports direct sampling of IF signals up to ~150 MHz with minimal amplitude distortion, as verified in Figure 34 of the Rev. G datasheet. The device achieves 49 dB SNR and 65 dBc SFDR at 70 MHz input, confirming usable performance well into the VHF band.
Does the AD9287ABCPZ-100 require an external voltage reference?
No, the AD9287ABCPZ-100 includes an internal 1.0 V reference with ±21 ppm/°C drift and ±30 mV output error. It can operate in buffered internal reference mode (SENSE = AVDD) or accept external differential reference (REFT/REFB) - eliminating need for external reference ICs in most applications. The VREF pin serves as both input and output depending on SENSE configuration.
How many serial LVDS data lanes does the AD9287ABCPZ-100 provide?
The AD9287ABCPZ-100 provides eight LVDS data lanes: four differential pairs (D+ A/D− A through D+ D/D− D), one per ADC channel. Each pair serially transmits 8-bit offset-binary data at 800 Mbps (100 MSPS × 8 bits) with embedded frame synchronization via FCO and data capture timing via DCO.
What is the pipeline latency of the AD9287ABCPZ-100, and why does it matter?
The AD9287ABCPZ-100 has a fixed pipeline latency of 8 clock cycles, as specified in Table 4 of the Rev. G datasheet. This deterministic delay is critical for time-sensitive applications like ultrasound beamforming and digital downconversion, where precise inter-channel phase alignment and synchronous processing across multiple ADCs must be maintained without variable FIFO buffering.
Can the AD9287ABCPZ-100 operate with a 3.3 V supply?
No - the AD9287ABCPZ-100 is specified only for 1.8 V AVDD and DRVDD supplies, with absolute maximum ratings of +2.0 V. Operation outside 1.7 V to 1.9 V violates specifications and risks parametric failure or damage. Its LVDS outputs are designed for 1.8 V termination; interfacing to 3.3 V logic requires level-shifting circuitry.
