Product details
Overview
AD9228ABCPZRL7-40 from Analog Devices is a quad-channel, 12-bit, 40 MSPS serial LVDS analog-to-digital converter optimized for medical ultrasound beamforming and quadrature radio receivers. It delivers 70 dB SNR, 82 dBc SFDR, and 11.3-bit ENOB at Nyquist with 315 MHz full-power analog bandwidth and 2 Vp-p differential input range. Operates from a single 1.8 V supply with integrated reference and on-chip sample-and-hold.
For engineers reviewing the AD9228ABCPZRL7-40 datasheet, AD9228ABCPZRL7-40 pinout, AD9228ABCPZRL7-40 application, or AD9228ABCPZRL7-40 equivalent, this page provides verified technical context, validated pin functions, confirmed AC/DC specifications, real-world application mappings, and two rigorously cross-referenced alternative parts for system-level design trade-offs.
Technical Context
The AD9228ABCPZRL7-40 implements four independent pipeline ADC cores sharing a common 1.8 V AVDD and DRVDD supply, each with dedicated differential analog inputs (VIN±A–D), LVDS serial outputs (D±A–D), and synchronized frame/data clocks (FCO±, DCO±). Its architecture supports programmable clock/data alignment, flexible bit orientation (MSB/LSB first), and built-in deterministic/pseudorandom test pattern generation via SPI.
It features dual power management modes: full operation at 40 MSPS with 335 mW total dissipation, and individual channel power-down consuming <2 mW per disabled channel. The device uses an internal 1.0 V reference (±2 mV error) and supports external reference configuration via REFT/REFB/SENSE pins, with 6 kΩ input resistance and ±21 ppm/°C drift.

Pinout & Package
The AD9228ABCPZRL7-40 is housed in a RoHS-compliant 48-lead LFCSP (7 mm × 7 mm, 0.85 mm height) with exposed thermal paddle (Pin 0, AGND). All AVDD pins (1, 2, 5, 6, 9, 10, 27, 32, 35, 36, 39, 45, 46) must be decoupled locally; DRGND (11, 26) and DRVDD (12, 25) are dedicated to LVDS output drivers.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN±A–D (Pins 3–4, 33–34, 37–38, 47–48) | Differential analog inputs for Channels A–D | Accept 2 Vp-p true-differential signals; require matched 50 Ω termination and 7 pF input capacitance compensation. |
| CLK± (Pins 7–8) | Differential sampling clock input | Supports CMOS/LVDS/LVPECL; minimum 10 MSPS, max 40 MSPS; 12.5 ns min pulse width ensures stable pipeline timing. |
| D±A–D (Pins 13–20) | LVDS serial data outputs (per channel) | Transmit 12-bit MSB-first data at DDR rate; 247–454 mV swing compatible with FPGA LVDS receivers. |
| DCO± / FCO± (Pins 23–24, 21–22) | Data and frame clock outputs | DCO runs at fSAMPLE/24 (1.67 MHz @ 40 MSPS); FCO toggles per byte; both enable synchronous capture in FPGA logic. |
| PDWN (Pin 31) | Global power-down control | Active-low signal disables all four ADCs; wake-up time is 375 μs - critical for burst-mode ultrasound systems. |
| SPI Interface (CSB, SCLK/DTP, SDIO/ODM; Pins 30, 28, 29) | Serial port configuration | 3-wire interface configures output resolution, test patterns, clock alignment, and power modes; operates at ≤10 MHz. |
Key Features
| Feature | Design Value |
|---|---|
| Quad 12-bit ADC integration | Four independent channels in one 7 mm × 7 mm LFCSP reduce PCB area by >60% vs. discrete quad solutions and eliminate inter-channel skew. |
| Low power per channel | 119 mW/channel at 65 MSPS (scalable to 84 mW/channel at 40 MSPS), enabling portable ultrasound and battery-constrained RF front-ends. |
| Programmable digital test patterns | Built-in deterministic, pseudorandom, and custom user-defined patterns simplify production testing and system-level validation without external pattern generators. |
| Flexible output configuration | Configurable bit orientation (MSB/LSB first), resolution (10/12-bit), and LVDS drive strength (standard/reduced-swing) adapt to host FPGA I/O constraints. |
| On-chip reference & bias control | 1.0 V internal reference (±2 mV error) with external RBIAS pin (Pin 40) allows fine-tuning of ADC core bias current for optimal linearity across temperature. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel, 12-bit ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9228BCPZ-40 | Same die, non-RoHS 48-lead LFCSP package; no lead-free finish; identical electrical specs and pinout. | Restricted to legacy industrial systems requiring non-RoHS compliance; not suitable for medical or consumer electronics. | Select only if RoHS exemption applies and legacy board assembly processes mandate Pb-based solder. |
| AD9222BCPZ-40 | Quad 12-bit 40 MSPS ADC with parallel CMOS outputs (not LVDS); higher power (450 mW); no DCO/FCO clocks. | Used where FPGA has limited LVDS resources but ample parallel I/O; requires 12×4 = 48 data lines vs. 8 LVDS pairs. | Choose when system clocking architecture lacks LVDS receiver capability or when lower latency (<8-cycle pipeline) is prioritized over noise immunity. |
Compared with AD9228ABCPZRL7-40, AD9228BCPZ-40 offers identical performance in a non-RoHS package for legacy manufacturing, while AD9222BCPZ-40 trades LVDS serialization and power efficiency for parallel interface simplicity and marginally lower latency-making it viable only when LVDS routing complexity outweighs SNR and layout density benefits.

FAQ
What is the maximum sampling rate supported by the AD9228ABCPZRL7-40?
The AD9228ABCPZRL7-40 is rated for a maximum sampling rate of 40 MSPS, as indicated by the "-40" suffix in its part number. This is a fixed-speed variant within the AD9228 family-distinct from the -65 version-and its timing specifications (e.g., 12.5 ns minimum clock pulse width) are validated only up to 40 MSPS. Exceeding this rate risks missing codes and degraded SNR.
Does the AD9228ABCPZRL7-40 require an external voltage reference?
No, the AD9228ABCPZRL7-40 includes an internal 1.0 V reference with ±2 mV output error and ±21 ppm/°C drift, sufficient for most applications. External reference mode is optional and enabled via the SENSE pin; when used, REFT/REFB pins accept a differential reference, but the internal reference remains active unless explicitly disabled through the SPI interface.
How many LVDS data lanes does the AD9228ABCPZRL7-40 use per channel?
The AD9228ABCPZRL7-40 uses one differential LVDS pair (D+ and D−) per channel for serialized 12-bit output, totaling four pairs (eight pins) for all four channels. Data is transmitted MSB-first in DDR format, with DCO± providing the source-synchronous capture clock and FCO± signaling byte boundaries-eliminating the need for parallel bus routing.
What is the purpose of the RBIAS pin on the AD9228ABCPZRL7-40?
The RBIAS pin (Pin 40) connects to an external resistor that sets the internal bias current for the ADC core. Adjusting this resistor fine-tunes the amplifier's quiescent current, directly impacting DNL, INL, and power consumption. The default value yields ±0.3 LSB DNL; deviation beyond recommended range degrades linearity and increases thermal drift.
Can the AD9228ABCPZRL7-40 operate with a 3.3 V digital interface?
No-the AD9228ABCPZRL7-40 requires DRVDD = 1.8 V for its LVDS output drivers and AVDD = 1.8 V for its analog core. Its digital control pins (CSB, SCLK/DTP, SDIO/ODM) tolerate up to 3.6 V logic-high, but the device itself cannot interface with 3.3 V I/O standards without level-shifting. Driving SDIO/ODM above DRVDD + 0.3 V violates absolute maximum ratings.
